Abstract | CONTEXT: Potentilla fulgens Wall. ex Hook (Rosaceae) is a potent medicinal plant of the Western Himalayas, where its roots are traditionally used by the local people of Uttaranchal (India) to treat wounds and tiger bites. OBJECTIVE: The present study scientifically evaluates the wound healing activity of P. fulgens ethanol root extract (EPF) and its ethyl acetate fraction (PFEA) on experimental rats. MATERIALS AND METHODS:
Wounds were inflicted on animals by using both excision and incision models. The wounded animals were treated for 16 days with EPF (oral: 200-400 mg/kg and topical: 5-10% w/w) and PFEA (oral: 75 mg/kg; topical: 1.75% w/w). Various physical ( wound contraction, epithelialization rate, tensile strength) and biochemical parameters ( hydroxyproline, hexosamine, proteins, DNA) were examined during the study. Oxidant product (lipidperoxidase), antioxidant enzymes ( catalase, superoxide-dismutase) and reduced glutathione were determined. Morphological and histopathological studies of the skin tissues were monitored. RESULTS: A significant (p < 0.05) wound healing property was observed when the animals were treated topically with EPF (10% w/w) and PFEA (1.75% w/w). A significantly (p < 0.05) increased in the levels of hydroxyproline, hexosamine, protein and DNA up to 59.22, 70.42, 61.01 and 60.00% was observed, respectively. This effect was further demonstrated by the morphological and histopathological representation, thus showing significant (p < 0.05) re-epethelialization on the healing area. EPF and PFEA also showed significant (p < 0.05) antioxidant activity. CONCLUSIONS: The present study provided the scientific evidence, where P. fulgens rich in polyphenolic components possess remarkable wound healing activities, thereby supporting the traditional claims.
