英文摘要	Preparative high-speed counter-current chromatography (hsccc) was successfully used for isolation and purification of quercetin-3-o-l-rhamnoside from the ethyl acetate extract of the leaves of acer truncatum bunge using a two-phase-system composed of ethyl acetate-ethanol-water at a volume ratio of 5:1:5 (v/v/v). in a single operation, 41.9 mg of quercetin-3-o-l-rhamnoside was obtained from 366 mg of the crude extract. high-performance liquid chromatography (hplc) analyses of the ccc fraction revealed that the purity of quercetin-3-o-l-rhamnoside was over 96%. its structure was identified by ms, h-1 nmr and c-13 nmr. quercetin-3-o-l-rhamnoside was obtained from this plant for the first time.
