A novel dimeric procyanidin glucoside,catechin 3-O-acetate-(4α→8)-catechin 3-O-acetate-3′-O-β-D-glucopyranoside (1),along with five flavonoids and one lignan were isolated from the aerial parts of Polygonum aviculare.Their structures were elucidated by spectroscopic analyses including 1D,2D NMR,MS and CD methods.
