To investigate the constituents from the fruit dregs of Rhus chinensis.
The constituents were isolated and purified by chromatography on silica gel,Sephadex LH-20,RP-C18 and Pre-TLC and recrystalization. The structures were identified on the basis of the chemical evidence,spectroscopic data.
Ten compounds were obtained and elucidated as m-digalloyl acid( 1),ethyl-m-digallate( 2),apigenin( 3),kaempferol( 4),quercetin( 5),3,7-dimethoxy-5,3’,4’-trihydroxy-flavone( 6),quercitrin( 7),kaempferol-3-O-α-L-rhamnoside( 8),myricetrin( 9) and quercetin-3-O-( 4″-methoxy)-α-L-rahmnopyranosyl( 10),respectively.
