title: [Chemical constituents from Lespedeza virgata].
abstract: 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.
