Elephantopus scaber and Clinacanthus nutans are traditionally used as wound healing herb The objective of the present study isto develop a new polyherbal formulation by comparison the herbal combination of Elephantopus scaber and Clinacanthus nutansas an in vitro antioxidant activity with their individual herbal activity followed by fractionation of polyherbal formulation forin vivo wound healing activities and identification of bioactive compounds from their active fractions Antioxidant activity wasperformed in vitro by DPPH scavenging antioxidant activity followed by in vivo wound healing activities using excision woundmodel incision wound model and burn wound model Toxicity of the fractions of the polyherbal formulation was performedby a dermal toxicity test The result showed that Elephantopus scaber crude extract on the basis of EC
50performs a much faster
action (1567 120583gmL) but with less inhibition (8766) as compared to the combination of the new polyherbal formulation ofcrude extract (30 120583gmL) The polyherbal formulation has the highest inhibition (8949) at the same dose as compared toElephantopus scaber (8766) In comparison among all crude and fractions of new polyherbal formulation it was found that theethyl acetate fraction of polyherbal formulation has the fastest activity (EC
501483 120583gmL)with inhibition (8928) Furthermore
during evaluation of wound contraction on excision and incision woundmodel ethyl acetate fraction possesses the highest activitywith (P lt 0001) and (P lt 00001) respectively During burn wound model aqueous fraction (P lt 0001) possesses the highestactivity followed by an ethyl acetate fraction (P lt 00001) LC-MS analysis discovered the presence of several flavonoid-basedcompounds that work synergistically with sesquiterpene lactone and other bioactive compounds In conclusion flavonoid increasesthe antioxidant activity that surges the rate of wound contraction and works synergistically with other bioactive compounds
1 Introduction
Everyone experiences a fair share of wounds during thecourse of their lives The impaired and aberrant woundhealing imposes a huge financial burden in the developedworld and is an insurmountable problem in the undevelopedone Many new approaches such as gene therapy and tissueengineered skin have met with limited success Conven-tional treatment of wound consists of nonsteroidal anti-inflammatory drugs (NSAIDs) antibiotics and topical corti-costeroidwhich havemany drawbacks All of themhave somenegative impact on healing [1 2] Herbal wound products
have been an area of remarkable growth to understand thedetails of the wound healing response The field of biologicwound products aims to accelerate healing by augmentingor modulating inflammatory mediators such as eicosanoidscytokines nitric oxide and various growth factors [3] Herb-herb combinations have been used in traditional AyurvedicUnani Chinese and Peruvian medicine practice for thou-sands of years yet scientific evidence of potential bioactivecompounds and their therapeutic benefits is lacking [4 5]
The selection of herbs is based upon their activity andimportance worldwide Clinacanthus nutans Lindau is used

for the treatment of burns eczema and herpes simplex It haslong been used as a traditional medicine for the treatment ofinsect and snakebites and skin rashes [6] Payayor (Clinacan-thus nutans) is a herbal therapy popular in Southeast AsiaA small study suggests that herbal Payayor may be superiorto benzydamine for prevention of oral mucositis [7] Leavesand even the whole plant ofClinacanthus nutans possess anti-inflammatory properties [8] The plant contains lupeol 120573-sitosterol stigmasterol botulin andmyricyl alcohol [9 10] Italso contains six known C-glycosyl flavones isolated from n-BuOH and a water soluble portion of the methanolic extractof the stems and leaves such as vitexin isovitexin shafto-side isomollupentin 7-O-120573-glucopyranoside orientin andisoorientin Five sulfur-containing glucosides were isolatedfrom the n-butanol soluble portion of a methanolic extractof the stems and leaves of plant material [11] A mixtureof cerebrosides and monoacylmonogalactosylglycerol wereseparated from the leaves of Clinacanthus nutans [9] Cli-nacanthus nutans commonly known in Malaysia as BelalaiGajah identifies as areas of initial focus under Entry PointProject (EPP) by Government of Malaysia [12]
Elephantopus scaber is commonly known in Malaysiaas Tutup Bumi Hydroalcoholic extract possesses anti-inflammatory activity A higher dose of compound signif-icantly reduced carrageenan-induced pedal edema (57)and formalin-induced pedal edema in rats (58) Ethanolicextract of leaves has shown significant antiasthmatic activitywound healing and nephroprotective activities along with itsprominent antiplatelet activity Deoxyelephantopin isolatedfrom the ethanolic extract of leaves promotes significantwound healing activity by increasing cellular proliferationthe formation of granulation tissue and synthesis of collagenand by increasing the rate of wound contraction [13] Teng-Khia-U a polyherbal formulation containing Elephantopusscaber is a Taiwan traditional medicine formulated for treat-ing nephritis edema dampness chest pain and fevercoughof pneumonia and scabiesarthralgia that was caused by thewound Researchers have shown that Teng-Khia-U possessedhepatoprotective and anti-inflammatory activity [14 15]This research affords an opportunity to develop new herbalformulation using Clinacanthus nutans and Elephantopusscaber to determine the antioxidant profile in comparisonwith individual herbs The active fractions of the polyherbalformulationwill further evaluate for its in vivowoundhealingactivity and their bioactive compounds The objective ofthe study was an investigation of the in vitro antioxidantactivity of Clinacanthus nutans Elephantopus scaber andpolyherbal extract of both medicinal herbs followed by theirfractionation After the antioxidant activity fractions of poly-herbal extract were further evaluated for their wound healingactivities Furthermore the suggested idea of investigatingbioactive compounds from active polyherbal fractions willhelp to identify several classes of phytochemicals such asflavonoids that are strongly associated with antioxidant andwound healing activity
2 Material and Method
21 Plant Material The leaf sample of these plant species wascollected from the soil of Agrotech Research Centre Institute
Of Sustainable Agrotechnology University Malaysia PerlisSg ChuchuhCampus Padang Besar PerlisThe samples werebrought to the laboratory and washed under running waterto get rid of dirt They were then dried under shade for twoweeksThematerials were pulverized in an electric mixer andpreserved in labeled glass bottles that were sealed and kept inthe refrigerator for later use
22 Preparation of Plant Extract The conventional Soxhletextraction apparatus has been used consisting of a condensera Soxhlet chamber and an extraction flask The time periodfor Soxhlet extraction was 12 hours 10 gm of dried andground leaves of Clinacanthus nutans Elephantopus scaberand combination of both herbs in equal amount (1 1)was placed in a Soxhlet apparatus and extracted with 50aqueous ethanol for 16 hours The crude extract solutionsobtained were then concentrated using a vacuum rotaryevaporator (Eyela Rotavap N-1200 vacuum controller-NVC-2200 Eyela water bath OSB-2100 Eyela chiller CCA-1111Rikakikai Co Ltd Tokyo) at a temperature of 50ndash60∘C The50 ethanol extract was fractionated using different solventsnamely hexane chloroform ethyl acetate n-butanol andwater (Figure 1)The supernatant was filtered usingWhatmannumber 1 sheet pooled and concentrated using vacuumrotary evaporatorThematerials were dried in an oven at 37∘Cfor 2 days Dried powder was stored in screw-capped glassbottles and kept in a refrigerator at 4∘C until further use
23 Cream Formulation 20 gm of powder of Clinacanthusnutans and Elephantopus scaber was extracted by Soxhletextraction Filter it 150mL of a solution of the polyherbalformulation is mixed with equal amount of infused olive oilAfter then we add 120mg of honey 100mL of rest of solutionof polyherbal extract and 20 g of beeswax
24 Free Radical Scavenging Activity Determination Thestable 22-diphenyl-1-picrylhydrazyl (DPPH) was used fordetermination of free radical scavenging activity of theextracts with fewmodifications [16] Different concentrations(20ndash200120583gmL) of each crude herbal extract were addedat an equal volume to an ethanolic solution of DPPH(01mM) After 30min at room temperature the absorbancewas recorded at 517 nm using UVVisible Spectrophotometer(UV-1800 Shimadzu Japan) The experiment was repeatedfor three times Ascorbic acid was used as positive controlsThe radical scavenging activity was expressed as the inhibi-tion percentage and monitored as per the equation DPPHradical scavenging = (AC minus ASAC) times 100 AC = absorbanceof control and AS = absorbance of the sample solutionEC50
values denote the concentration of the sample whichis required to scavenge 50 of DPPH free radicals It wascalculated from inhibition curve
25 Experimental Animals Healthy Swiss albino mice ofeither sex with more than 6ndash8 weeks of age and weightaround 45ndash60 g were used The animals were kept at roomtemperature (27 plusmn 2∘C 70ndash80 humidity 12 h lightdarkcycle) acclimatize for at least 72 h prior to the procedureCommercial food pellets and water were supplied ad libitum

262 Epithelization Time Measurement The period ofepithelization was calculated as the number of days requiredfor falling off of the dead tissue remnants without any residualraw wound [20]
27 Incision Wound Model On a wounding day animalswere anesthetized in the same manner described for excisionwound model The dorsal fur of each mouse was then shavedand 3 cm long longitudinal paravertebral incision was madethrough the skin and subcutaneous tissue The parted skinwas then sutured 1 cm apart using a surgical thread andcurved needle The continuous thread on both wound edgeswas tightened for the good closure of the wounds (Figure 2)After 24 h of wound creation (on 1st day) animals weretreated as described under grouping and dosing section witha topical formulation of the vehicle extract or standard dailyfor nine days leaving out the last group which did not receiveany of the interventions The sutures were removed on day 8after incision and tensile strength was measured on the 11thpostwounding day [21]
28 BurnWoundModel The animals were anesthetized withdiethyl ether and their dorsal surface was shaved with asterile blade The shaved area was disinfected with 70(vv) ethanol Burn wounds were created on dorsal part ofshaved rats using a metal rod (25 cm diameter) heated to80ndash85∘C and exposed for 20 s After 24 h dead tissues wereexcised using sterile surgical blade [22] Measurement ofwound contraction and epithelization time was calculatedusing excision wound model
29 Acute Dermal Toxicity For dermal toxicity a total of 10(5 females and 5 males) rats were used Animals showingnormal skin texture were housed individually in a cage andacclimatized to the laboratory condition for five days priorto the test Following acclimation around 10 of the bodysurface area fur was shaved 24 h before the study from the

2 Evidence-Based Complementary and Alternative Medicine
for the treatment of burns eczema and herpes simplex It haslong been used as a traditional medicine for the treatment ofinsect and snakebites and skin rashes [6] Payayor (Clinacan-thus nutans) is a herbal therapy popular in Southeast AsiaA small study suggests that herbal Payayor may be superiorto benzydamine for prevention of oral mucositis [7] Leavesand even the whole plant ofClinacanthus nutans possess anti-inflammatory properties [8] The plant contains lupeol 120573-sitosterol stigmasterol botulin andmyricyl alcohol [9 10] Italso contains six known C-glycosyl flavones isolated from n-BuOH and a water soluble portion of the methanolic extractof the stems and leaves such as vitexin isovitexin shafto-side isomollupentin 7-O-120573-glucopyranoside orientin andisoorientin Five sulfur-containing glucosides were isolatedfrom the n-butanol soluble portion of a methanolic extractof the stems and leaves of plant material [11] A mixtureof cerebrosides and monoacylmonogalactosylglycerol wereseparated from the leaves of Clinacanthus nutans [9] Cli-nacanthus nutans commonly known in Malaysia as BelalaiGajah identifies as areas of initial focus under Entry PointProject (EPP) by Government of Malaysia [12]
Elephantopus scaber is commonly known in Malaysiaas Tutup Bumi Hydroalcoholic extract possesses anti-inflammatory activity A higher dose of compound signif-icantly reduced carrageenan-induced pedal edema (57)and formalin-induced pedal edema in rats (58) Ethanolicextract of leaves has shown significant antiasthmatic activitywound healing and nephroprotective activities along with itsprominent antiplatelet activity Deoxyelephantopin isolatedfrom the ethanolic extract of leaves promotes significantwound healing activity by increasing cellular proliferationthe formation of granulation tissue and synthesis of collagenand by increasing the rate of wound contraction [13] Teng-Khia-U a polyherbal formulation containing Elephantopusscaber is a Taiwan traditional medicine formulated for treat-ing nephritis edema dampness chest pain and fevercoughof pneumonia and scabiesarthralgia that was caused by thewound Researchers have shown that Teng-Khia-U possessedhepatoprotective and anti-inflammatory activity [14 15]This research affords an opportunity to develop new herbalformulation using Clinacanthus nutans and Elephantopusscaber to determine the antioxidant profile in comparisonwith individual herbs The active fractions of the polyherbalformulationwill further evaluate for its in vivowoundhealingactivity and their bioactive compounds The objective ofthe study was an investigation of the in vitro antioxidantactivity of Clinacanthus nutans Elephantopus scaber andpolyherbal extract of both medicinal herbs followed by theirfractionation After the antioxidant activity fractions of poly-herbal extract were further evaluated for their wound healingactivities Furthermore the suggested idea of investigatingbioactive compounds from active polyherbal fractions willhelp to identify several classes of phytochemicals such asflavonoids that are strongly associated with antioxidant andwound healing activity
2 Material and Method
21 Plant Material The leaf sample of these plant species wascollected from the soil of Agrotech Research Centre Institute
Of Sustainable Agrotechnology University Malaysia PerlisSg ChuchuhCampus Padang Besar PerlisThe samples werebrought to the laboratory and washed under running waterto get rid of dirt They were then dried under shade for twoweeksThematerials were pulverized in an electric mixer andpreserved in labeled glass bottles that were sealed and kept inthe refrigerator for later use
22 Preparation of Plant Extract The conventional Soxhletextraction apparatus has been used consisting of a condensera Soxhlet chamber and an extraction flask The time periodfor Soxhlet extraction was 12 hours 10 gm of dried andground leaves of Clinacanthus nutans Elephantopus scaberand combination of both herbs in equal amount (1 1)was placed in a Soxhlet apparatus and extracted with 50aqueous ethanol for 16 hours The crude extract solutionsobtained were then concentrated using a vacuum rotaryevaporator (Eyela Rotavap N-1200 vacuum controller-NVC-2200 Eyela water bath OSB-2100 Eyela chiller CCA-1111Rikakikai Co Ltd Tokyo) at a temperature of 50ndash60∘C The50 ethanol extract was fractionated using different solventsnamely hexane chloroform ethyl acetate n-butanol andwater (Figure 1)The supernatant was filtered usingWhatmannumber 1 sheet pooled and concentrated using vacuumrotary evaporatorThematerials were dried in an oven at 37∘Cfor 2 days Dried powder was stored in screw-capped glassbottles and kept in a refrigerator at 4∘C until further use
23 Cream Formulation 20 gm of powder of Clinacanthusnutans and Elephantopus scaber was extracted by Soxhletextraction Filter it 150mL of a solution of the polyherbalformulation is mixed with equal amount of infused olive oilAfter then we add 120mg of honey 100mL of rest of solutionof polyherbal extract and 20 g of beeswax
24 Free Radical Scavenging Activity Determination Thestable 22-diphenyl-1-picrylhydrazyl (DPPH) was used fordetermination of free radical scavenging activity of theextracts with fewmodifications [16] Different concentrations(20ndash200120583gmL) of each crude herbal extract were addedat an equal volume to an ethanolic solution of DPPH(01mM) After 30min at room temperature the absorbancewas recorded at 517 nm using UVVisible Spectrophotometer(UV-1800 Shimadzu Japan) The experiment was repeatedfor three times Ascorbic acid was used as positive controlsThe radical scavenging activity was expressed as the inhibi-tion percentage and monitored as per the equation DPPHradical scavenging = (AC minus ASAC) times 100 AC = absorbanceof control and AS = absorbance of the sample solutionEC50
values denote the concentration of the sample whichis required to scavenge 50 of DPPH free radicals It wascalculated from inhibition curve
25 Experimental Animals Healthy Swiss albino mice ofeither sex with more than 6ndash8 weeks of age and weightaround 45ndash60 g were used The animals were kept at roomtemperature (27 plusmn 2∘C 70ndash80 humidity 12 h lightdarkcycle) acclimatize for at least 72 h prior to the procedureCommercial food pellets and water were supplied ad libitum

Animal handling and care were carried out throughout theexperiment following international laboratory animal useand care guidelines [17]
251 Grouping and Dosing of Animals For excision modelsix groups of mice each containing four animals was usedThe first group was treated with ethyl acetate fractionThe second and third groups were treated with n-butanoland aqueous fraction respectively The fourth group wastreated with a polyherbal cream The fifth and sixth groupswere treated with control without drug and standard usingpovidone iodine respectively All administrations were per-formed topically with amaximumquantity of 250mgkgdayFor burn wound model five groups of mice containing four
mice per group were used The first group was treated withethyl acetate fraction The second and third groups weretreated with n-butanol and aqueous fraction respectivelyThe fourth and fifth groups were treated with standard usingpovidone iodine and control without drug respectively Alladministrations were performed topically with a maximumquantity of 250mgkgday For incision wound model allanimals were treated in a similar fashionwith excisionwoundmodel For acute dermal toxicity all animals were treated ina similar fashion with burn wound model

was then marked and the full thickness of the marked areawas carefully excised by using sharp sterilized scissors After24 h of wound creation the sample was applied gently oncedaily according to the respective grouping as described undergrouping and dosing section to cover the wounded areauntil complete healing was achievedWound contraction andepithelization period were monitored Wound contractionwas measured as millimeter (mm2) and percent contractionevery day until complete epithelization was achieved [18]
261 Measurement of Wound Contraction The wound heal-ing progress was evaluated by measuring wound areas usinga transparency sheet and a permanent marker The evaluatedsurface area was used to calculate the percentage of woundcontraction taking initial size of the wound (225mm2) as100 [19] as shown below

262 Epithelization Time Measurement The period ofepithelization was calculated as the number of days requiredfor falling off of the dead tissue remnants without any residualraw wound [20]
27 Incision Wound Model On a wounding day animalswere anesthetized in the same manner described for excisionwound model The dorsal fur of each mouse was then shavedand 3 cm long longitudinal paravertebral incision was madethrough the skin and subcutaneous tissue The parted skinwas then sutured 1 cm apart using a surgical thread andcurved needle The continuous thread on both wound edgeswas tightened for the good closure of the wounds (Figure 2)After 24 h of wound creation (on 1st day) animals weretreated as described under grouping and dosing section witha topical formulation of the vehicle extract or standard dailyfor nine days leaving out the last group which did not receiveany of the interventions The sutures were removed on day 8after incision and tensile strength was measured on the 11thpostwounding day [21]
28 BurnWoundModel The animals were anesthetized withdiethyl ether and their dorsal surface was shaved with asterile blade The shaved area was disinfected with 70(vv) ethanol Burn wounds were created on dorsal part ofshaved rats using a metal rod (25 cm diameter) heated to80ndash85∘C and exposed for 20 s After 24 h dead tissues wereexcised using sterile surgical blade [22] Measurement ofwound contraction and epithelization time was calculatedusing excision wound model
29 Acute Dermal Toxicity For dermal toxicity a total of 10(5 females and 5 males) rats were used Animals showingnormal skin texture were housed individually in a cage andacclimatized to the laboratory condition for five days priorto the test Following acclimation around 10 of the bodysurface area fur was shaved 24 h before the study from the

Animal handling and care were carried out throughout theexperiment following international laboratory animal useand care guidelines [17]
251 Grouping and Dosing of Animals For excision modelsix groups of mice each containing four animals was usedThe first group was treated with ethyl acetate fractionThe second and third groups were treated with n-butanoland aqueous fraction respectively The fourth group wastreated with a polyherbal cream The fifth and sixth groupswere treated with control without drug and standard usingpovidone iodine respectively All administrations were per-formed topically with amaximumquantity of 250mgkgdayFor burn wound model five groups of mice containing four
mice per group were used The first group was treated withethyl acetate fraction The second and third groups weretreated with n-butanol and aqueous fraction respectivelyThe fourth and fifth groups were treated with standard usingpovidone iodine and control without drug respectively Alladministrations were performed topically with a maximumquantity of 250mgkgday For incision wound model allanimals were treated in a similar fashionwith excisionwoundmodel For acute dermal toxicity all animals were treated ina similar fashion with burn wound model

was then marked and the full thickness of the marked areawas carefully excised by using sharp sterilized scissors After24 h of wound creation the sample was applied gently oncedaily according to the respective grouping as described undergrouping and dosing section to cover the wounded areauntil complete healing was achievedWound contraction andepithelization period were monitored Wound contractionwas measured as millimeter (mm2) and percent contractionevery day until complete epithelization was achieved [18]
261 Measurement of Wound Contraction The wound heal-ing progress was evaluated by measuring wound areas usinga transparency sheet and a permanent marker The evaluatedsurface area was used to calculate the percentage of woundcontraction taking initial size of the wound (225mm2) as100 [19] as shown below
Wound contraction

262 Epithelization Time Measurement The period ofepithelization was calculated as the number of days requiredfor falling off of the dead tissue remnants without any residualraw wound [20]
27 Incision Wound Model On a wounding day animalswere anesthetized in the same manner described for excisionwound model The dorsal fur of each mouse was then shavedand 3 cm long longitudinal paravertebral incision was madethrough the skin and subcutaneous tissue The parted skinwas then sutured 1 cm apart using a surgical thread andcurved needle The continuous thread on both wound edgeswas tightened for the good closure of the wounds (Figure 2)After 24 h of wound creation (on 1st day) animals weretreated as described under grouping and dosing section witha topical formulation of the vehicle extract or standard dailyfor nine days leaving out the last group which did not receiveany of the interventions The sutures were removed on day 8after incision and tensile strength was measured on the 11thpostwounding day [21]
28 BurnWoundModel The animals were anesthetized withdiethyl ether and their dorsal surface was shaved with asterile blade The shaved area was disinfected with 70(vv) ethanol Burn wounds were created on dorsal part ofshaved rats using a metal rod (25 cm diameter) heated to80ndash85∘C and exposed for 20 s After 24 h dead tissues wereexcised using sterile surgical blade [22] Measurement ofwound contraction and epithelization time was calculatedusing excision wound model
29 Acute Dermal Toxicity For dermal toxicity a total of 10(5 females and 5 males) rats were used Animals showingnormal skin texture were housed individually in a cage andacclimatized to the laboratory condition for five days priorto the test Following acclimation around 10 of the bodysurface area fur was shaved 24 h before the study from the

from leaves of Clinacanthus nutans and Elephantopus scaberdetected with MS in negative and positive modes The spec-tral data from the peaks were identical and the identificationwas based on the LC-MSMS data and comparison with theliteratureTheoverview is shown in the chromatographic dataof ethyl acetate the n-butanol and aqueous fraction which issummarized in Tables 5 6 and 7 respectively A maximumnumber of flavonoids were found in ethyl acetate fractionfollowed by an aqueous fraction and an n-butanol fractionFlavonoids play an important role in wound healing [24ndash26]There is another important bioactive compound also presentin all fractions Among them sesquiterpene lactone and phe-nolic compounds are also present that showed the synergisticeffect Although no report was found on the synergistic effectof flavonoids and sesquiterpene lactone further investigationis going on to understand the relationship between flavonoidsand sesquiterpene lactone List of possible flavonoids is alsomentioned along with their structure in Figure 7
4 ConclusionPolyherbal formulation is a common practice in herbalismAn effort has been made to develop a new polyherbalformulation in the treatment of the wound This is the firstdocument that fractionates polyherbal extract and identifiesthe possible bioactive compound This paper has establisheda correlation between wound healing activity and possiblebioactive compounds This paper indicates that flavonoidsmay perform an important role in the healing of the woundA further experiment is required to isolate the possiblebioactive compound from ethyl acetate and an aqueousfraction of polyherbal extract and to evaluate the isolatedcompounds on different wound model

was then marked and the full thickness of the marked areawas carefully excised by using sharp sterilized scissors After24 h of wound creation the sample was applied gently oncedaily according to the respective grouping as described undergrouping and dosing section to cover the wounded areauntil complete healing was achievedWound contraction andepithelization period were monitored Wound contractionwas measured as millimeter (mm2) and percent contractionevery day until complete epithelization was achieved [18]
261 Measurement of Wound Contraction The wound heal-ing progress was evaluated by measuring wound areas usinga transparency sheet and a permanent marker The evaluatedsurface area was used to calculate the percentage of woundcontraction taking initial size of the wound (225mm2) as100 [19] as shown below
Wound contraction

262 Epithelization Time Measurement The period ofepithelization was calculated as the number of days requiredfor falling off of the dead tissue remnants without any residualraw wound [20]
27 Incision Wound Model On a wounding day animalswere anesthetized in the same manner described for excisionwound model The dorsal fur of each mouse was then shavedand 3 cm long longitudinal paravertebral incision was madethrough the skin and subcutaneous tissue The parted skinwas then sutured 1 cm apart using a surgical thread andcurved needle The continuous thread on both wound edgeswas tightened for the good closure of the wounds (Figure 2)After 24 h of wound creation (on 1st day) animals weretreated as described under grouping and dosing section witha topical formulation of the vehicle extract or standard dailyfor nine days leaving out the last group which did not receiveany of the interventions The sutures were removed on day 8after incision and tensile strength was measured on the 11thpostwounding day [21]
28 BurnWoundModel The animals were anesthetized withdiethyl ether and their dorsal surface was shaved with asterile blade The shaved area was disinfected with 70(vv) ethanol Burn wounds were created on dorsal part ofshaved rats using a metal rod (25 cm diameter) heated to80ndash85∘C and exposed for 20 s After 24 h dead tissues wereexcised using sterile surgical blade [22] Measurement ofwound contraction and epithelization time was calculatedusing excision wound model
29 Acute Dermal Toxicity For dermal toxicity a total of 10(5 females and 5 males) rats were used Animals showingnormal skin texture were housed individually in a cage andacclimatized to the laboratory condition for five days priorto the test Following acclimation around 10 of the bodysurface area fur was shaved 24 h before the study from the

Figure 3 Comparison between all fractions with respect to control in excision wound model
2013 Raw data obtained from different wound models areexpressed as mean plusmn SEM 119875 values less than 005 were con-sidered to be statistically significant The data were analyzedusingGraphPad Prism version 7 forWindows and differencesamong groups were compared by one-way ANOVA followedby Dunnettrsquos test
3 Results and Discussion31 Free Radical Scavenging Activity Determination All theresults were reported based on the dry sample after Soxhletextraction Based on the results the test conducted forevaluating antioxidant activity in Clinacanthus nutans Ele-phantopus scaber and a combination of an equal proportionof both leaves and their fraction (n-hexane chloroformethyl acetate n-butanol aqueous fractions) showed that theDPPH radical scavenging activity increased with the increasein concentration Clinacanthus nutans Elephantopus scaberand new polyherbal combination crude extract exhibitedantioxidant activity at all the concentration of test solutionswith maximum inhibition by new polyherbal formulation(8949) With the increasing concentration of leaves extract(20ndash200120583gmL) the percentage of antioxidant activity alsoincreased On the basis of the highest inhibition theformulation was further fractionated into n-hexane chloro-form ethyl acetate n-butanol and aqueous fractions Duringevaluation of fractions of new polyherbal formulation itwas found that maximum inhibition was achieved byan n-butanol fraction (8997) followed by ethyl acetate(8928) and aqueous fraction (8620) respectively EC

32 Excision Wound Model Significant wound contractionwas initiated from day 6 in Group I (P lt 005) and epithe-lization was completed on day 12 (P lt 0001) followed byGroups II (P lt 0001) and III (P lt 00001) on day 12 and day 15respectively (Table 2 Figure 3) Figure 2 represents woundcontraction among all fractions as compared to control inexcision wound model
33 Incision Wound Model The tensile strength of animalstreated with the ethyl acetate fraction was significantly higher(119875 lt 00001) than the standard followed by n-butanol (119875 lt00001) and aqueous fraction (119875 lt 00001) although noapparent difference was detected with cream of polyherbalextract (119875 lt 0001) as compared to n-butanol fraction(Table 3)

from leaves of Clinacanthus nutans and Elephantopus scaberdetected with MS in negative and positive modes The spec-tral data from the peaks were identical and the identificationwas based on the LC-MSMS data and comparison with theliteratureTheoverview is shown in the chromatographic dataof ethyl acetate the n-butanol and aqueous fraction which issummarized in Tables 5 6 and 7 respectively A maximumnumber of flavonoids were found in ethyl acetate fractionfollowed by an aqueous fraction and an n-butanol fractionFlavonoids play an important role in wound healing [24ndash26]There is another important bioactive compound also presentin all fractions Among them sesquiterpene lactone and phe-nolic compounds are also present that showed the synergisticeffect Although no report was found on the synergistic effectof flavonoids and sesquiterpene lactone further investigationis going on to understand the relationship between flavonoidsand sesquiterpene lactone List of possible flavonoids is alsomentioned along with their structure in Figure 7
4 ConclusionPolyherbal formulation is a common practice in herbalismAn effort has been made to develop a new polyherbalformulation in the treatment of the wound This is the firstdocument that fractionates polyherbal extract and identifiesthe possible bioactive compound This paper has establisheda correlation between wound healing activity and possiblebioactive compounds This paper indicates that flavonoidsmay perform an important role in the healing of the woundA further experiment is required to isolate the possiblebioactive compound from ethyl acetate and an aqueousfraction of polyherbal extract and to evaluate the isolatedcompounds on different wound model

from leaves of Clinacanthus nutans and Elephantopus scaberdetected with MS in negative and positive modes The spec-tral data from the peaks were identical and the identificationwas based on the LC-MSMS data and comparison with theliteratureTheoverview is shown in the chromatographic dataof ethyl acetate the n-butanol and aqueous fraction which issummarized in Tables 5 6 and 7 respectively A maximumnumber of flavonoids were found in ethyl acetate fractionfollowed by an aqueous fraction and an n-butanol fractionFlavonoids play an important role in wound healing [24ndash26]There is another important bioactive compound also presentin all fractions Among them sesquiterpene lactone and phe-nolic compounds are also present that showed the synergisticeffect Although no report was found on the synergistic effectof flavonoids and sesquiterpene lactone further investigationis going on to understand the relationship between flavonoidsand sesquiterpene lactone List of possible flavonoids is alsomentioned along with their structure in Figure 7
4 ConclusionPolyherbal formulation is a common practice in herbalismAn effort has been made to develop a new polyherbalformulation in the treatment of the wound This is the firstdocument that fractionates polyherbal extract and identifiesthe possible bioactive compound This paper has establisheda correlation between wound healing activity and possiblebioactive compounds This paper indicates that flavonoidsmay perform an important role in the healing of the woundA further experiment is required to isolate the possiblebioactive compound from ethyl acetate and an aqueousfraction of polyherbal extract and to evaluate the isolatedcompounds on different wound model

4 ConclusionPolyherbal formulation is a common practice in herbalismAn effort has been made to develop a new polyherbalformulation in the treatment of the wound This is the firstdocument that fractionates polyherbal extract and identifiesthe possible bioactive compound This paper has establisheda correlation between wound healing activity and possiblebioactive compounds This paper indicates that flavonoidsmay perform an important role in the healing of the woundA further experiment is required to isolate the possiblebioactive compound from ethyl acetate and an aqueousfraction of polyherbal extract and to evaluate the isolatedcompounds on different wound model

from leaves of Clinacanthus nutans and Elephantopus scaberdetected with MS in negative and positive modes The spec-tral data from the peaks were identical and the identificationwas based on the LC-MSMS data and comparison with theliteratureTheoverview is shown in the chromatographic dataof ethyl acetate the n-butanol and aqueous fraction which issummarized in Tables 5 6 and 7 respectively A maximumnumber of flavonoids were found in ethyl acetate fractionfollowed by an aqueous fraction and an n-butanol fractionFlavonoids play an important role in wound healing [24ndash26]There is another important bioactive compound also presentin all fractions Among them sesquiterpene lactone and phe-nolic compounds are also present that showed the synergisticeffect Although no report was found on the synergistic effectof flavonoids and sesquiterpene lactone further investigationis going on to understand the relationship between flavonoidsand sesquiterpene lactone List of possible flavonoids is alsomentioned along with their structure in Figure 7
4 ConclusionPolyherbal formulation is a common practice in herbalismAn effort has been made to develop a new polyherbalformulation in the treatment of the wound This is the firstdocument that fractionates polyherbal extract and identifiesthe possible bioactive compound This paper has establisheda correlation between wound healing activity and possiblebioactive compounds This paper indicates that flavonoidsmay perform an important role in the healing of the woundA further experiment is required to isolate the possiblebioactive compound from ethyl acetate and an aqueousfraction of polyherbal extract and to evaluate the isolatedcompounds on different wound model

from leaves of Clinacanthus nutans and Elephantopus scaberdetected with MS in negative and positive modes The spec-tral data from the peaks were identical and the identificationwas based on the LC-MSMS data and comparison with theliteratureTheoverview is shown in the chromatographic dataof ethyl acetate the n-butanol and aqueous fraction which issummarized in Tables 5 6 and 7 respectively A maximumnumber of flavonoids were found in ethyl acetate fractionfollowed by an aqueous fraction and an n-butanol fractionFlavonoids play an important role in wound healing [24ndash26]There is another important bioactive compound also presentin all fractions Among them sesquiterpene lactone and phe-nolic compounds are also present that showed the synergisticeffect Although no report was found on the synergistic effectof flavonoids and sesquiterpene lactone further investigationis going on to understand the relationship between flavonoidsand sesquiterpene lactone List of possible flavonoids is alsomentioned along with their structure in Figure 7
4 ConclusionPolyherbal formulation is a common practice in herbalismAn effort has been made to develop a new polyherbalformulation in the treatment of the wound This is the firstdocument that fractionates polyherbal extract and identifiesthe possible bioactive compound This paper has establisheda correlation between wound healing activity and possiblebioactive compounds This paper indicates that flavonoidsmay perform an important role in the healing of the woundA further experiment is required to isolate the possiblebioactive compound from ethyl acetate and an aqueousfraction of polyherbal extract and to evaluate the isolatedcompounds on different wound model

from leaves of Clinacanthus nutans and Elephantopus scaberdetected with MS in negative and positive modes The spec-tral data from the peaks were identical and the identificationwas based on the LC-MSMS data and comparison with theliteratureTheoverview is shown in the chromatographic dataof ethyl acetate the n-butanol and aqueous fraction which issummarized in Tables 5 6 and 7 respectively A maximumnumber of flavonoids were found in ethyl acetate fractionfollowed by an aqueous fraction and an n-butanol fractionFlavonoids play an important role in wound healing [24ndash26]There is another important bioactive compound also presentin all fractions Among them sesquiterpene lactone and phe-nolic compounds are also present that showed the synergisticeffect Although no report was found on the synergistic effectof flavonoids and sesquiterpene lactone further investigationis going on to understand the relationship between flavonoidsand sesquiterpene lactone List of possible flavonoids is alsomentioned along with their structure in Figure 7
4 ConclusionPolyherbal formulation is a common practice in herbalismAn effort has been made to develop a new polyherbalformulation in the treatment of the wound This is the firstdocument that fractionates polyherbal extract and identifiesthe possible bioactive compound This paper has establisheda correlation between wound healing activity and possiblebioactive compounds This paper indicates that flavonoidsmay perform an important role in the healing of the woundA further experiment is required to isolate the possiblebioactive compound from ethyl acetate and an aqueousfraction of polyherbal extract and to evaluate the isolatedcompounds on different wound model
