title: [Studies on chemical constituents in herb of Myricaria bracteata].
abstract: OBJECTIVE
  To study the chemical constituents of Myricaria bracteata.
  
  
  METHODS
  The chemical constituents were isolated by silica gel column chromatography and the structures were elucidated by spectroscopic methods.
  
  
  RESULTS
  Eleven compounds were obtained and identified as rhamnetin, 3,5,4'-trihydroxy-7,3'-dimethoxyflavone, 3,5,4'-trihydroxy-7-methoxyflavone, quercetin-3-O-alpha-L-rhamnopyranoside, kaempferol, quercetin, chrysoerio, gallic acid, gallic acid ethylester, beta-sitosterol, daucosterol.
  
  
  CONCLUSIONS
  All compounds were obtained from M. bracteata for the first time.
