Evaluation for Protective Effect of Rutin, a Natural Flavonoid, against HCl/Ethanol-Induced Gastric Lesions

In this study we investigated the protective effects of rutin, a natural plant flavonoid, on HCl/ethanol-induced gastric lesions in rats. Rutin showed the antioxidant activities, the acid-neutralizing capacities, and the inhibitory effects on the growth of Helicobacter pylori (H. pylori.), which are equivalent to control compounds. In addition, rutin significantly inhibited HCl/ethanol-induced gastric lesions. Antigastritic action of rutin may be associated with the antioxidant activities, acid-neutralizing capacities, anti-H. pylori action, and the stimulation of mucus secretion. From these results, we could suggest that rutin may be useful for the treatment and/or protection of gastritis.
