ETHNOPHARMACOLOGICAL RELEVANCE: In traditional Indian medicinal treatise there are several Ayurvedic formulations mentioned which have been claimed as potential wound healing agents like Madhu Ghrita and Jatyadi Taila. Jatyadi Taila (JT) is a medicated oil formulation (Taila) popularly used in the treatment of various topical wounds. AIM OF THE STUDY: Though JT has its composition recorded in ancient Ayurvedic texts, there have been minimal attempts to standardize its use in the management of wound. The current work evaluates the wound healing efficacy of JT and also provides evidence of the dermal absorption kinetics of Karanjin from JT. MATERIALS AND METHODS: JT was subjected to preliminary phytochemical evaluation. Therapeutically active marker components β-sitosterol, lupeol and karanjin were detected and separated using HPTLC. As a part of safety evaluation, skin irritation potential of JT was evaluated on rabbit skin. Excision wound model in rats were used to evaluate the wound healing efficacy of JT. Histopathological and biochemical evaluations of excised skin tissues at wound sites were carried out. The HPTLC method developed was also validated to evaluate the pharmacokinetics of Karanjin from JT after topical application on pinna of rabbit. RESULTS: Preliminary phytochemical evaluation of JT revealed presence of flavonoids, essential oils, tannins, glycosides, steroids and alkaloids while resins were found to be absent. HPTLC confirmed the presence of karanjin, lupeol and β-sitosterol in JT. JT was found to be non-irritant when applied to the skin of rabbits. Topical application of JT on excision wounds caused significantly faster reduction in wound area as compared to the application of modern topical formulation (Neosporin(®)) and untreated control wounds. Animals treated with JT showed significant increase in protein, hydroxyproline and hexosamine content in the granulation tissue when compared with the untreated controls. Wound healing potential of JT was found to be dose dependant. HPTLC method was successfully used to evaluate the pharmacokinetics of Karanjin after topical application of JT on rabbit pinna. CONCLUSIONS: Current work demonstrates a modern approach towards standardization of the use of traditional topical formulation JT. The results justify the traditional claim of JT for its use in the management of wounds. Copyright Â
