title: Evaluation of the antiulcerogenic activity of friedelan-3beta-ol and friedelin isolated from Maytenus ilicifolia (Celastraceae).
abstract: An easy methodology for triterpene isolation is shown. Evaluation in rats for antiulcer activity of friedelan-3beta-ol 1 and friedelin 2. The two triterpenes isolated from the leaves of Maytenus ilicifolia, did not decrease gastric ulcers when tested on indometacine induced ulcer model in rats.
