The purpose of the study was to elucidate the antiulcer activity of stem of Saccharum Officinarum (Poaceae) in albino rats against aspirin induced gastric ulcer, ethanol induced gastric ulcer and pylorus ligation induced gastric ulcer models. Groups of rats were fasted overnight, received ranitidine (20 mg/kg) as a standard and plant stem juice extract at dose of 0.75 mL/100 gm and 1.5 mL/100 gm as a treatment against aspirin induced gastric ulcer, ethanol induced gastric ulcer and pylorus ligation induced gastric ulcer. The treatment produced significant protection of ulcer induced by aspirin, ethanol and pylorus ligation induced ulcer. The extract also reduced ulcer index, volume of gastric content, free and total acidity, suggesting that extract possesses significant anti-ulcer activity.
