title: [Study on HPLC fingerprint characteristic analysis of Cordyceps sinensis and its similar products].
abstract: OBJECTIVE
  To study on HPLC fingerprint characteristic analysis of Cordyceps sinensis and its similar products.
  
  
  METHODS
  To determinate 13 samples of Cordyceps sinensis and its similar products by HPLC, and analyze the HPLC results with similar appraisal method and graphical methods of multivariate sample in two dimensional plane such as the methods of profile, radar chart and constellation graph.
  
  
  RESULTS
  The similar appraisal method might synthesize the similar degree in quantification, while the graphical methods such as profile graph, radar chart and constellation graph could show more details about the classification and the characteristic of varieties directly.
  
  
  CONCLUSIONS
  We recommend the combined application of similar appraisal method and the graphical methods due to its advantages on the judgment and characteristic analysis of fingerprint.
