Objective:
To evaluate the anti-ulcer activity of ethanol extract of leaves of Polyalthia longifolia (Sonn.) Thwaites.
Materials And Methods:
The ethanol extract of Polyalthia longifolia was investigated for its anti-ulcer activity against aspirin plus pylorous ligation induced gastric ulcer in rats, HCl -Ethanol induced ulcer in mice and water immersion stress induced ulcer in rats at 300 mg/kg body weight.p.o.
Results:
A significant (P < 0.01, P < 0.001) anti ulcer activity was observed in all the models. Pylorous ligation showed significant (P< 0.01) reduction in gastric volume, free acidity and ulcer index as compared to control. It also showed 89.71% ulcer inhibition in HCl- Ethanol induced ulcer and 95.3% ulcer protection index in stress induced ulcer.
Conclusion:
This present study indicates that P. longifolia leaves extract have potential anti ulcer activity in the three models tested.
