摘要：

A novel cycloartane-type glycoside was isolated from the aerial parts of Astragalus trojanus along with the known glycosides astragaloside II, astragaloside IV, astragaloside VII, brachyoside B, brachyoside C and the pterocarpan derivative maackiain. The structure of 1 was determined by spectral methods (1-D and 2-D NMR, and FABMS) and established as 3-O-beta-[alpha-L-arabinopyranosyl(1 --> 2)beta-D-xylopyranosyl]-6-O-beta-D-glucopyranosyl-20(R),24(S)-epoxy-3 beta,6 alpha,16 beta,25-tetrahydroxycycloartane.
