Two new cholestane bisdesmosides (1, 2) based upon (22S)-cholest-5-ene-3 beta,16 beta,22-triol with an acetyl group at the sugar moiety and three new ones (3-5) based upon (22S)-cholest-5-ene-1 beta,3 beta,16 beta,22-tetrol, along with a known cholestane glycoside, were isolated from the bulbs of Galtonia candicans. The structures of the new compounds were determined by spectroscopic analysis and chemical transformations.
从网球花的鳞茎中分离出两种基于(22S)-胆甾-5-烯-3β,16β,22-三醇且糖部分带有乙酰基的新胆甾烷双糖苷(1, 2)，以及三种基于(22S)-胆甾-5-烯-1β,3β,16β,22-四醇的新化合物(3 - 5)，还有一种已知的胆甾烷糖苷。通过光谱分析和化学转化确定了新化合物的结构。
