Abstract
A new bidesmosidic triterpenoidal saponin 3-O-[beta-D-glucopyranosyl-(1-->4)-beta-D-glucopyranosyl-(1-->4)-alpha-L - arabinopyranosyl]-hederagenin-28-O-[alpha-L-rhamnopyranosyl- (1-->4)-beta-D- glucopyranosyl-(1-->6)-beta-D-glucopyranosyl] ester, was isolated from the roots of Symphytum officinale. The structure was assigned by chemical methods and spectral analysis (1H, 13C, DEPT, NMR, EI-MS and FAB-MS) including 1H-1H COSY, 1H-13C COSY and HOHAHA. The prosapogenin of this saponin is also a new compound.
