title: [Studies on flavonoids of Anaphalis sinica].
abstract: OBJECTIVE
  To investigate the chemical constituents of Anaphalis sinica.
  
  
  METHODS
  Various chromatographic techniques were employed for the isolation and purification of the constituents. The structures were elucidated by chemical and spectral analysis.
  
  
  RESULTS
  Six flavonoid compounds were isolated and identified as kaempferol, tiliroside, quercetin, quercetin -3-O-beta-D-glucosides, scutellarin, 5,7-dihydroxy-8-methoxyflavone and one pyrone were isolated and identified as helipyrone.
  
  
  CONCLUSIONS
  All of these compounds was isolated from the plant for the first time.
