Abstract:
A new bidesmosidic triterpenoidal saponin of hederagenin was isolated from the ethanolic extract of the roots of Symphytum officinale L. Its structure was elucidated by using 1H NMR, 1H-1H COSY NMR, heteronuclear 1H-13C correlated spectroscopy (heteroCOSY), 13C NMR, DEPT, FAB mass spectrometry and chemical evidence as 3-O-alpha-L-arabinopyranosyl]-hederagenin-28-O-[beta-D-gluco pyranosyl- (-->4)-beta-D-glucopyranosyl-(1-->6)-beta-D-glucopyranosyl]ester.
