Abstract: A novel cycloartane-typeglycoside was isolated from the aerialparts of Astragalustrojanus 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-β-[α-l-arabinopyranosyl(1→2)β-d-xylopyranosyl]-6-O-β-d-glucopyranosyl-20(R),24(S)-epoxy-3β,6α,16β,25-tetrahydroxycycloartane.
