Abstract

Two new isolariciresinol-type lignan glycosides were isolated from Vitis thunbergii (Vitaceae) along with some oligostilbenes. Their structures were elucidated as (+)-3α-O-α-L-rhamnopyranosyl-5-methoxyisolariciresinol and (—)-3α-O-β-D-xylopyranosyl-6-O-β-D-glucopyranosylisolariciresinol, respectively, on the basis of the spectral evidence
