摘要：
Two new sapogenins, named (20S, 24R)-3 beta,20,21 beta,25-tetrahydroxy-21,24-cyclodammarane (1) and 3 beta-hydroxyetio-17 beta-dammaranic acid (2), were isolated from the alkaline hydrolysate of Gynostemma pentaphyllum saponins. Their structures were elucidated by spectroscopic methods. (C) 2011 Yu Qing Zhao. Published by Elsevier B.V. on behalf of Chinese Chemical Society. All rights reserved.
