Abstract

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.
