Context: Spondias mombin Linn (Anacardiaceae) and Ficus exasperata Valh (Moraceae) are botanicals with known phytotherapeutic potentials in the traditional system of medicine in the world.Objective: The objective of this study is to investigate the quantitative polyphenolic constituents and gastroprotective effects of aqueous leaf extracts of Spondias mombin and Ficus exasperata against indomethacin-induced gastric ulcer in rats.Materials and methods: Ulceration was induced by a single oral administration of indomethacin (30mg/kg body weight (b.w.)). Ulcerated rats were orally administered with esomeprazole (a reference drug) at a dose of 20mg/kg body weight, and Spondias mombin and Ficus exasperata at a dose of 100 and 200mg/kg b.w. once daily for 21 d after ulcer induction. Gastric secretions and antioxidant parameters were thereafter evaluated.Results: The significantly increased (p<0.05) ulcer index, gastric volume, malondialdehyde level, and pepsin activity by indomethacin were effectively reduced by 65.40, 36.47, 45.71, and 53.79%, respectively, following treatment with F. exasperata at 200mg/kg b.w. S. mombin at this regimen also attenuated these parameters by 71.70, 46.62, 50.16, and 55.73%. Moreover, the extracts significantly increase the reduced activity of superoxide dismutase as well as pH and mucin content in the ulcerated rats.Discussion and conclusion: These findings are indicative of gastroprotective and antioxidative potentials of the extracts which is also evident in the degree of % inhibition against ulceration. The available data in this study suggest that the extracts proved to be capable of ameliorating indomethacin-induced gastric ulceration and the probable mechanisms are via antioxidative and proton pump inhibition.
