title: [Studies on chemical constituents in bud of Artemisia scoparia (II)].
abstract: OBJECTIVE
  To investigate the chemical constituents in flower bud of Artemisia scoparia.
  
  
  METHODS
  The constituents were isolated and purified by means of various chromatographic methods, and spectroscopic methods were used to identify their structures.
  
  
  RESULTS
  Four flavones were isolated and their structures were identified as hyperin (V), eupafolin (VI), pedalitin (VII), 5,7,2',4'-tetrahydroxy-6,5'-dimethoxyflavone (VIII).
  
  
  CONCLUSIONS
  Compounds V, VI, VII, VIII were obtained from this plant for the first time.
