Isolation and identification of a novel flavonoid from Penthorum chinense P.
A novel flavonoid, pinocembrin-7-O-[3''-O-galloyl-4'',6''-hexahydroxydiphenoyl]-beta-glucose (1) was isolated from the whole plant of Penthorum chinense P., along with four known compounds, pinocembrin-7-O-beta-glucoside, quercitrin, quercetin-3-O-rhamnoside and gallic acid. The structures were established by spectroscopic analysis.
