Gastroprotective effect of leaf extracts of Basella alba var. alba against experimental gastric ulcers in rats
The aqueous and ethanol extracts of the leaves of Basella alba L. var. alba Wight, Basellaceae, were investigated for antiulcer activity on rats employing the pylorus ligation and ethanol induced ulcer models. The various gastric secretion parameters such as total acidity, free acidity, gastric acid volume, pH and histopathological parameters such as ulcer index and percent protection were comparatively examined between control, test and standard groups. The antiulcer activity of aqueous extract of B. alba (AEBA) and ethanol extract of B. alba (EEBA) were studied in rats treated with the doses of 1 mL/kg of absolute ethanol, 200 and 400 mg of test extracts and 20 mg/kg of famotidine for control, test and standard groups respectively in both the models. The animals pretreated with AEBA and EEBA showed a dose-dependent protection against gross damaging action of ethanol and pylorus ligation on gastric mucosa of animals. Histopathological evaluation also revealed that Group I treated with absolute ethanol showed severe gastric mucosal damage. The AEBA and EEBA showed 68.25 and 58.11% protection in gastric mucosal damage as compared to control group. Both the extracts of B. alba var. alba were able to decrease the gastric acidity and increase the mucosal defense in the gastric mucosal area. This study indicate that B. alba var. alba possesses significant gastroprotective effect and the same is substantiated by the histopathological examination of the ulcerated stomachs of the animals.
