| Abstract: | OBJECTIVE: To investigate the chemical constituents of Lespedeza virgata. METHOD: The constituents were isolated by column chromatography and their structures were elucidated by chemical properties and spectroscopic evideuce. RESULT: 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). CONCLUSION: Seven components are isolated from L. virgata for the first time. |
