Abstract
Ethanol and acetone extracts of Lannea coromandelica (Houtt) merr (Anacardiaceae) barks in the form of simple ointments screened for wound-healing activity by incision and excision wound on male Wister rats. In excision wound model, more than 95% wound healing was recorded in treated groups by 16 days of post surgery, whereas only 85.40% was observed in control group. Significant (P<0.01) epithelialization was observed in the groups treated with both ethanol and acetone extract ointments. In incision wound model higher breaking strength were observed 82.43%, 63.77% in ethanol and acetone extracts treated groups respectively suggested higher collagen re-deposition than the control group. Framycetin sulphate (1%) was used as standard in both incision and excision wound models. Finally, histopathological studies confirmed the wound healing properties. The results shown that Lannea coromandelica extract has potent wound healing activity by in terms of significant wound contraction and increased tensile strength. Since wound healing is severely influenced by microbial infection, this study was extended to evaluate antimicrobial activity apart from wound healing activity. The antimicrobial activity was determined by disc diffusion method.
