To investigate the chemical constituents of Lespedeza virgata. The constituents were isolated by column chromatography and their structures were elucidated by chemical properties and spectroscopic evideuce. Seven components were isolated and identified as quercetin 3-O-[2"-O-( E'-6"-O-feruloyl)-beta-D-glucopyranosyl]-beta-D-galact opyranoside (1), kaempferol-7-O-L-rhamnopyranoside (2), 7-O-alpha-L-rhamnopyransyl-kaempeferol-3-O-beta-D-glucopyranoside (3), quercetine (4), E-beta-hydroxycinnamic acid (5), protocatechuic acid (6), p-hydroxybenzoic (7). Seven components are isolated from L. virgata for the first time.
