Strychnos potatorum (Fam: Loganiaceae) Linn seeds are useful in the treatment of gastropathy in Indian traditional system of medicine. The present study describes the antiulcerogenic potential of S. potatorum Linn seeds on aspirin plus pyloric ligation (Aspirin+PL)-induced gastric ulcer model to substantiate its folklore claim. The seed powder (SPP) and aqueous extract of the seeds (SPE) at two doses 100 and 200 mg/kg, p.o. prevented ulcer formation by decreasing acid secretory activity and increasing the mucin activity in rats. The antiulcerogenic potential was further confirmed by the histopathological studies of stomach mucosa. The results indicate that SPP and SPE exhibit antiulcerogenic activity by both antisecretory and mucoprotective actions. The mucoprotective action of SPP and SPE may be due to the presence of polysaccharides in seeds. The antiulcerogenic potential of SPP and SPE was compared with the standard antiulcer drug, ranitidine.
