title: [Identification on genuine and pseudo shayuanzi collected from different place by HPLC fingerprint].
abstract: OBJECTIVE
  To establish the identification method for genuine and pseudo Shayuanzi by HPLC fingerprint.
  
  
  METHODS
  The flavone, a kind of active composition in genuine (Astragalus complanatus) and analysed species was analysed by RP-HPLC.
  
  
  RESULTS
  The fingerprints of genuine Shayuanzi collected from different places showed the similar characteristics, but they were different from those of pseudo species A. adsuragen and A. sinicus.
  
  
  CONCLUSIONS
  The HPLC fingerprint can be an identifing method for Shayuanzi.
