A New Active Steroidal Saponin from<i>Anemarrhena asphodeloides</i>

Abstract

A new active steroidal saponin, anemarsaponin B, was isolated from the rhizomes of Anemarrhina asphodeloides. The structure of anemarsaponin B was elucidated as 26-O-beta-D-glucopyranosylfurost-20(22)-ene-3 beta, 26-diol-3-O-beta-D-glucopyranosyl-(1----2)-beta-D-galactopyranoside by chemical and spectral studies. Preliminary pharmacological tests showed that anemarsaponin B could inhibit PAF-induced rabbit platelet aggregation in vitro.
