title: [Studies on flavonoid constituents from herbs of Artemisia ordosica II].
abstract: OBJECTIVE
  To study the chemical constituents of herbs of Artemisia ordosica.
  
  
  METHODS
  The chemical constituents were isolated and repeatedly purified on silica gel column and the structures were elucidated by the NMR spectra and physicochemical properties.
  
  
  RESULTS
  Eight flavones were obtained and they were identified as isosakuranetin, 7, 4'-dimethylaro madendrin, acacetin, cirsimaritin, rhamnetin, eupatolin, 5, 7, 2', 4'-tetrahydroxy-6, 5'-dimethoxyflavone, hyperoside.
  
  
  CONCLUSIONS
  All the compounds were obtained from herbs of A. ordosica for the first time.
