Özet

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 of officinale. The structure was assigned by chemical methods and spectral analysis (H-1, C-13, DEFT, NMR, EI-MS and FAB-MS) including H-1-H-1 COSY, H-1-C-13 COSY and HOHAHA. The prosapogenin of this saponin is also a new compound.
