摘要：

From the stem of Parthenocissus quinquefolia, two new resveratrol oligomers, parthenocissins A and B, were isolated in addition to three known stilbenes. The structures, 1Z-2 alpha,3 beta-2-(3,5-dihydroxyphenyl)-2,3-dihydro-3-(4-hydroxyphenyl)-1-[(4-hydroxyphenyl)methylene]-1H-indene-4,6-diol (parthenocissin A) and 1Z,2 alpha,3 beta,4'alpha,5'beta-2-(3,5-dihydroxyphenyl)-2,3-dihydro-3(4-hydroxyphenyl)-1-[{4'-(3,5-dihydroxyphenyl)-3'(4-hydroxyphenyl)-4,5-dihydrofurano(2',3':4,3)-phenyl}methylene]-1H-indene-4,6-diol (parthenocissin B), were elucidated by the analysis of spectral data including 2D-NMR and NOE experiment.
