    Abstract:
    The present study was designed to investigate the effect of Mimusops elengi (Sapotaceae) against experimental gastric ulcers. The 50% alcoholic extract of Mimusops elengi (Ext E) and its different fractions namely ethyl acetate (Ext E1), n-butanol (Ext E2), methanol (Ext E3) and aqueous (Ext E4) were studied (p.o.) against ethanol-induced gastric damage. Ext E1 was also studied in ethanol-induced, pylorus-ligated and water-immersion plus stress-induced gastric ulcer models. Ranitidine HCl (80 mg kg(-1)) was used as a reference standard. In ethanol-induced gastric ulcer model, pantoprazole (20 mg kg(-1)) was also used as a reference standard. Ext E1 tested in mice up to the dose of 5000 mg kg(-1) (p.o.) did not produce any sign of toxicity. Ext E at the doses of 50, 100, 300 and 500 mg kg(-1) and its different fractions (100 mg kg(-1)) showed reduction in gastric ulceration (P < 0.05). Ext E1 at the doses of 10, 50 and 100 mg kg(-1) showed dose-dependent inhibition of gastric lesions against ethanol-induced gastric damage. In 19 h pylorus-ligated animals, Ext E1 at 50 and 100 mg kg(-1) doses showed significant reduction in ulcer index (P < 0.05). Significant reduction was also observed in total acidity, volume of gastric acid secretion, total acid output and pepsin activity (P < 0.05) when compared with the control group. Besides, Ext E1 showed increase in the mucosal glycoproteins that was evident from significant rise in total carbohydrates to protein ratio (TC:PR ratio) (P < 0.05), which is an indication of mucin activity. Ext E1 also showed protection against water-immersion plus stress-induced gastric lesions that was evident from dose-dependent decrease in ulcer index (P < 0.05), score for intensity (P < 0.05) and total lesion area (P < 0.05) when compared with the control group. It can be concluded from our study that Ext E1 possesses anti-ulcer activity against experimental gastric ulcers. The mechanism of anti-ulcer activity can be attributed to decrease in gastric acid secretory activity along with strengthening of mucosal defensive mechanisms.
