title: [Determination of coumarins content in Radix Angelicae dahuricae by HPLC and UV].
abstract: OBJECTIVE
  To determine the coumarins content in Radix Angelicae Dahuricae (Baizhi).
  
  
  METHODS
  The total content of coumarins was determined by UV. The content of imperatorin, isoimperatorin and oxypeucedanin hydrate in different samples was carriedut by HPLC.
  
  
  RESULTS
  The processing method and the medicinal position have great effect on the coumarin content.
  
  
  CONCLUSIONS
  The content of oxypeucedanin hydrate in Baizhi was determined. This method can be used for quality control of Baizhi.
