Abstract

The rhizomes of Tacca chantrieri have been analyzed as part of a systematic study on saponin constituents of medicinal plants. This has resulted in the isolation of three new bisdesmosidic furostanol saponins (1-3), two new bisdesmosidic pseudofurostanol saponins (4, 5), and two new pregnane glycosides (6, 7). Their structures were determined on the basis of extensive spectroscopic studies and a few chemical transformations.

摘要

作为对药用植物皂苷成分系统研究的一部分，对箭根薯的根茎进行了分析。这导致分离出三种新的双糖链呋甾烷醇皂苷（1-3）、两种新的双糖链假呋甾烷醇皂苷（4,5）和两种新的孕烷糖苷（6,7）。它们的结构是基于广泛的光谱研究和一些化学转化确定的。
