Gastroprotective Activity of Aerial Leaves of Allium cepa

The present study was performed to evaluate the Antiulcer activity of Methanolic extract of Allium cepa leaves (MEAC) in Albino rats. Antiulcer activity of MEAC was investigated by using Ethanol induced gastric mucosal damage and Pylorous ligated gastric ulcers. Evaluation was done on both models comparing with reference standard Omeprazole (20mg/kg). The parameters taken to assess anti-ulcer for pylorus ligation method were volume gastric secretion, pH, free acidity, total acidity and ulcer index. In vivo studies were carried on the plant extract and results were found that protection of the Methanolic extract of Allium cepa leaves against characteristic lesions may be due to both reduction in gastric acid secretion and gastric cycloprotein and this may be due to the presence of Flavanoids. In this study we observed that, Methanolic extract of leaves of Allium cepa (MEAC) provides significant antiulcer activity against gastric ulcers in rats. The result of MEAC showed significant reduction in the ulcer index, when compared to control. The antiulcer activity extract may be attributed to their flavanoids content and antioxidant property. These findings indicate that MEAC display potential antiulcerogenic activity.
