Antiradical and antiulcer effect of Sonneratia apetala Buch-Ham leaves against alcohol induced gastric mucosal injury

Abstract Introduction: Sonneratia apetala Buch-Ham is a true mangrove inhabitant in Indian Sunderban and it is used in folk medicine for digestive disorders. Method: Hydro-methanolic (20:80) extract of Sonneratia apetala leaves (SA) was chemically standardized by HPTLC and evaluated for its antiradical and gastro-protective properties. Phenolics and flavonoids present in SA were determined and antiradical activities were assessed by in vitro methods like, DPPH (1,1-diphenyl-2-picrylhydrazyl), nitric oxides, superoxides, hydroxyl and ABTS (2,2/-azino-bis-3-ethyl benzthiazoline-6-sulphonic acid). Further, gastro-protective efficacy of SA was assessed in alcohol (50% v/v, 5 ml/kg) induced oxidative ulceration in rats. Results: Chemically standardized SA exhibited presence of polyphenolic compounds. It also showed strong antiradical properties. Oral administrations of SA (125 mg/kg and 250 mg/kg) significantly protected gastric mucosal membrane from ulcerative damage caused by alcohol, similar to Omeprazole (20 mg/kg) in rats. Moreover, SA treatment significantly reduced the elevation of lipid peroxides; while enhanced the concentration of glutathione and catalase in gastric mucosa in respect to ethanol induced untreated control rats. Conclusions The results obtained from this study suggest Sonneratia apetala leaf has antioxidant properties and has capabilities to protect gastric mucosal injury caused by alcohol ingestion.
