作为药用植物皂苷成分系统研究的一部分，本文分析了茯苓根茎。这导致分离出三种新的双硅氧烷糠醇皂苷（1-3），两种新的双硅氧烷假糠醇皂苷（4,5）和两种新的孕烷苷（6,7）。它们的结构是在广泛的光谱研究和一些化学转变的基础上确定的。
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.
