TL;DR: Six compounds were isolated from the ethyl acetate extract of the tuberous root of Polygonum multiflorum by silical gel, ODS revsered-phase silica gel, Sephadex LH-20, and preparative HPLC and one is a new stilbene glycoside.
Abstract: Six compounds were isolated from the ethyl acetate extract of the tuberous root of Polygonum multiflorum by silical gel, ODS revsered-phase silica gel, Sephadex LH-20, and preparative HPLC. The structures were elucidated as column chromatography over： 2, 3, 5, 4'-tetrahydroxystilbene-2-O-(2″-O-p-hydroxybenzoyl)-β-D-glucoside(1),2, 3, 5, 4'-tetrahydroxystilbene-2-O-β-D-glucoside(2),2, 4, 6, 4'-tetrahydroxystilbene-2-O-β-D-glucoside(3), emodin-8-O-β-D-glucopyranoside(4), physcion-8-O-β-D-glucopyranoside(5), and 8-O-methyl-emodin(6) on the basis of spectral analysis. Compound 1 is a new stilbene glycoside.

TL;DR: The studies on chemistry and bioactivity of genus Polygonum mainly from 1990 were reviewed.
Abstract: The genus Polygonum(Polygonaceae)contains rich medicinal plantsAmong the 120 Polygonum species in China,81 species were recorded to have medicinal uses in traditional Chinese medicine and folk medicineFrom 1980s,more and more work including chemical and biological activity studies on this genus were reportedIn this paper,the studies on chemistry and bioactivity of genus Polygonum mainly from 1990 were reviewed
