Two new oligostilbenes from the stem of Parthenocissus quinquefolia

Abstract

Two new oligostilbenes, parthenocissins M (1) and N (2), together with two known compounds, miyabenol C (3) and ϵ-viniferin (4), were isolated from the stem of Parthenocissus quinquefolia. Their structures were elucidated by means of NMR, UV, IR, and MS data.
