Abstract

Twenty-eight protostane triterpenoids, including a new degraded one (1), nine new ones (2 - 10), and two new natural ones (11 and 12), have been isolated from the dried rhizomes of Alisma orientale. Alisol R (1) was the first 20,21,22,23,24,25,26,27-octanorprotostane triterpenoid. The absolute configurations of 25-methoxyalisol F (2) and 16β-hydroperoxyalisol B 23-acetate (3) were determined by X-ray diffraction analysis. In addition, alismaketone-B 23-acetate (28) showed potent vasorelaxant activity on endothelium-intact thoracic aorta rings precontracted with KCl.
