title: [Studies on chemical constituents in buds of Artemisia scoparia].
abstract: OBJECTIVE
  To investigate the chemical constituents in flower buds of Artemisia scoparia.
  
  
  METHODS
  The constituents were separated and purified by means of various chromatographic techniques, and their structures were determined on the basis of physical and chemical properties and spectral data.
  
  
  RESULTS
  Four flavones were isolated and their structures were identified as cirsilineol (I), cirsimaritin(II), arcapillin(III) and cirsiliol(IV) respectively.
  
  
  CONCLUSIONS
  Compounds I, III and IV were isolated from this plant for the first time.
