Three novel polyoxypregnane glycosides, volubiloside A, B and C (1-3), were isolated from the flowers of Dregea volubilis Linn., and their structures were elucidated as drevogenin D-3-O-β-D-glucopyranosyl (1→4)-6-deoxy-3-O-methyl-β-D-allopyranosyl (1→4)-β-D-cymaropyranosyl (1→4)-β-D-cymaropyranoside, drevogenin D-3-O-β-D-glucopyranosyl (1→4)-6-deoxy-3-O-methyl-β-D-allopyranosyl (1→4)-β-D-cymaropyranosyl (1→4)-β-D-digitoxopyranoside and drevogenin P-3-O-β-D-glucopyranosyl (1→4)-6-deoxy-3-O-methyl-β-D-allopyranosyl (1→4)-β-D-cymaropyranosyl (1→4)-β-D-cymaropyranoside, respectively, on the basis of extensive NMR experiments, MALDI-TOF MS, and some chemical strategies.
