title: [Studies on chemical constituents in bud of Artemisia scoparia (III)].
abstract: OBJECTIVE
  To investigate the chemical constituents in flower bud of Artemisia scoparia.
  
  
  METHODS
  The methanol extract was isolated by column chromatography with silica gel, polyamide and Sephadex LH-20 as packing materials and HPLC, six compounds were obtained and their structures were identified by UV, NMR and MS.
  
  
  RESULTS
  Six compounds were identified as beta-sitosterol (IX), 6,7-dimethoxycoumarin (X), 6-demethylcapillarisin (XI), capillartemisin B (XII), kumatakenin (XIII), isoscoploletin-beta-D-glucoside (XIV).
  
  
  CONCLUSIONS
  XI, XII, XIII and XIV were obtained from the plant for the first time, and XI is a new compound.
