Abstract

Two new pregnane glycosides, baseonemoside A and B, were isolated from the aerial parts of Baseonema acuminatum. Their structures were established as pregn-5-ene-3β,16α,20(S)-triol 3-O-β-D-cymaropyranosyl-(1→4)-β-D-digitoxopyranoside 20-O-β-D-glucopyranosyl-(1→2)-β-D-digitalopyranoside 1 and pregn-5-ene-3β,16α,20(S)-triol 3-O-β-D-cymaropyranosyl-(1→4)-β-D-cymaropyranosyl-(1→4)-β-D-digitoxopyranoside 20-O-β-D-glucopyranosyl-(1→2)-β-D-digitalopyranoside 2, respectively, on the basis of spectral evidence and chemical transformation.
