title: [Evaluating the quality of Angelica sinensis with fuzzy matter-element model based on variation coefficient weight].
abstract: OBJECTIVE
  To investigate the utilization of fuzzy matter-element model in evaluating the quality of Angelica sinensis.
  
  
  METHODS
  The quality of Angelica sinensis from different habitats was evaluated by determining six main compositions contained in the samples with fuzzy matter-element model based on variation coefficient weight.
  
  
  RESULTS
  Angelica sinensis collected from 22 hatitats were divided into three ranges based on the values of approach degrees.
  
  
  CONCLUSIONS
  Fuzzy matter-element model based on variation coefficient weight can judge the quality of Angelica sinensis objectively and feasibly.
