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.
