Abstract

C-nor-D-homo-homologues of cannogenin and uzarigenin glycosides were isolated along with known cardenolide glycosides from the frozen fresh leaves of Thevetia neriifolia. A bisdesmosidic tetraoside of 3 beta,14,21-trihydroxy-5 beta,14 beta-pregnan-20-one was also obtained from the polar fraction and the structure established.

摘要

从黄花夹竹桃的冷冻鲜叶中分离出了cannogenin和uzarigenin糖苷的C-去甲-D-高同系物以及已知的强心苷糖苷。还从极性部分获得了一种3β,14,21-三羟基-5β,14β-孕烷-20-酮的双糖苷四糖苷，并确定了其结构。
