Abstract

A new triterpenoidal saponin having hederagenin as the aglycone was isolated from the roots of SYMPHYTUM OFFICINALE L. The structure of this saponin was elucidated by FAB-MS, (1)H-, (13)C-NMR, 2D-NMR analyses and chemical studies as 3- O-[beta- D-glucopyranosyl-(1-->4)-alpha- L-arabinopyranosyl]-hederagenin 28- O-[beta- D-glucopyranosyl-(1-->6)-beta- D-glucopyranosyl] ester.
