Abstract
Two new cholestane bisdesmosides (1, 2) based upon (22S)-cholest-5-ene-3 be ta ,16 beta ,22-triol with an acetyl group at the sugar moiety and three ne w ones (3-5) based upon (22S)-cholest-5-ene-1 beta ,3 beta ,16 beta ,22-tet rol, 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.
