title: [Study on the flavonoids of Eupatorium lindleyanum].
abstract: OBJECTIVE
  Study on the flavonoids from the air part of Eupatorium lindleyanum.
  
  
  METHODS
  Alcohol percolation, silica gel column chromatography and re-crystallization et al.
  
  
  RESULTS
  Jaceosidin, kaempferol, quceritin, astragalin, trifolin and hypersoide were isolated from E. lindleyanum. Their structures were elucidated on the basis of spectral evidence.
  
  
  CONCLUSIONS
  Jaceosidin, kaempferol, quceritin, astragalin and trifolin were isolated from E. lindleyanum for the first time.
