[The antigastroulcerative activity of beta-sitosterol-beta-D-glucoside and its aglycone in rats].

Abstract

Beta-sitosterol-beta-D-glucoside and its aglycone (the major constituent of the seed oil of Hippophae rhamnoides L.) were investigated for their antigastroulcerative activity in rats. Two experimental gastric ulcer models were selected: chronic acetic acid-induced ulcers and cold stress-induced ulcers. Both the glucoside and its aglycone showed antiulcerative activity in chronic acetic acid-induced gastric ulcer models, and their effects were at least comparable to the effects of wishupin in combination with cimetidine. The effect of aglycone appears better than the glucoside's. Glucoside also showed visibly antiulcerative effects on cold stress-induced ulcers, but wishupin combined with cimetidine did not have such effects.
