title: [Study on the flavanone constitutes of Buddleja davidii].
abstract: OBJECTIVE
  To study the chemical constitutes of Buddleja davidii.
  
  
  METHODS
  The constitutes were isolated and purified by silica gel column chromatography, polyamide column chromatography and macroporous absorption resin and their structures were elucidated by spectroscopic analysis.
  
  
  RESULTS
  Seven compounds including Apigenin (1), Apigenin-7-O-beta-D-glucoside (2), Acacetin (3), Acacetin-7-O-beta-D-glucoside(4), Acacetin-7-O-alpha-L-rhamnopyranosyl-(1-6)-beta-D-glucopyranoside (5), Luteolin (6), Luteolin-7-O-beta-D-glueoside (7).
  
  
  CONCLUSIONS
  All these compounds are obtained from this plant for the first time.
