Wound healing activity of the leaf extracts of Ammannia baccifera L., Lythraceae, and Blepharis maderaspatensis (L.) B.Heyne ex Roth., Acanthaceae, was investigated by excision and incision wound healing models in rats. A phytochemical screening was done to determine the major constituents of the chloroform, ethyl acetate and ethanolic fractions of ethanolic leaf extracts. The excision and incision models were used to assess the effect of the plant extracts on wound healing in rats. Phytochemical screening reveals the presence of tannins, saponins, steroids, terpenoids, and flavonoids in the extract. The wound healing effect was comparatively evaluated with a standard drug Framycetin cream. Significant wound healing activity was observed for the creams prepared with 5% ethanol fraction of B. maderaspatensis and 5% chloroform fraction of A. baccifera ethanolic leaf extracts. The results of histopathological evaluation supported the outcome of both incision and excision wound models. Ethanolic fraction of B. maderaspatensis and chloroform fraction of A. baccifera exhibited marked wound healing activity. B. maderaspatensis extract displayed a remarkable wound healing activity compared to A. baccifera.

A series of benztriazoles bearing Mannich bases (2 -10) were synthesized from benztriazole by aminomethylation with formaldehyde and various substituted secondary amines. Titled compounds were synthesized by Mannich reaction and they were characterized by IR and ¹HNMR spectroscopy. All these Mannich bases were screened for hepatoprotective activity on carbon tetrachloride induced liver damage in rats. Only compounds 4 (250 mg/kg) protected significantly the animals from carbon tetrachloride induced hepatotoxicity. Compound 4 N-morpholinyl methyl benztriazole exhibited significant activity comparable to that of standard drug silymarin.
