Abstract

The protective effects of the ethylacetate fraction of persimmon leaves(PEF) against experimentally induced gastric mucosal damage and gastric ulcers were evaluated in ratss. In prophylatic study, 100 mg/kg ethylacetate fraction of persimmon leaves (PEFH) exhibited a total protection of 73.8% and 65.7% against HCl-ethanol and 0.2N NaOH-induced gastric mucosal membrane lesions, respectively, which was superior to cimetidine 50 mg/kg, a commonly used anti-ulcer drug. PEFH showed excellent anti-ulcer effects against pylorus ligation induced gastric ulcers, compared to the control group, however, 50 mg/kg ethylacetate fraction of persimmon leaves (PEFL) and PEFH did not affect ulcers induced by water immersion stress, and that is inferior to cimetidine 50 mg/kg. In conclusion, the results suggest that the ethylacetate fraction of persimmon leaves can be used both in prevention and treatment of experimentally induced gastric mucosal damage and ulcers.
