title: [Study on quality evaluation of Angelica sinensis by grey incidence degree method].
abstract: OBJECTIVE
  To evaluate the quality of Angelica sinensis based on Grey incidence degree method.
  
  
  METHODS
  Grey model was set up by determining four main compositions contained in the samples.
  
  
  RESULTS
  The result of quality evaluation on 21 samples by this model was as same as that of genuine medicinal materials.
  
  
  CONCLUSIONS
  Grey incidence degree method and the model can be used to evaluate the quality of Angelica sinensis.
