[Chemical constituents from Lespedeza virgata].
OBJECTIVE
To investigate the chemical constituents of Lespedeza virgata.


METHODS
The constituents were isolated by column chromatography and their structures were elucidated by chemical properties and spectroscopic evideuce.


RESULTS
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).


CONCLUSIONS
Seven components are isolated from L. virgata for the first time.
