title: [Isolation and elucidation of chemical constituents with antiviral action from yinqiaosan on influenza virus].
abstract: OBJECTIVE
  To study the chemical constituents with antiviral action from Yinqiaosan on influenza virus.
  
  
  METHODS
  Constituents were isolated by different kinds of column chromatography and their structures were elucidated with chemical and spectral methods.
  
  
  RESULTS
  Eleven chemical constituents were isolated and elucidated as arctiin, phillyrin, forsythiaside, liquiritigenin, liquiritin, genistein, formononetin, daidzein, glycitrin, 3,3',4-tri-omethlellagic acid and chlorogenic acid.
  
  
  CONCLUSIONS
  Genistein, daidzein, glycitrin and 3,3',4-tri-omethlellagic acid were isolated from Yinqiaosan for the first time.
