title: [Application of hierarchical cluster with high-performance liquid chromatography in the classification of genus Clinopodium chinensis].
abstract: OBJECTIVE
  To realize the relationships of the plants of genus C. chinensis in our country and confirm the feasible quality of the application of Hierarchical cluster in the classification of genus C. chinensis.
  
  
  METHODS
  The chemical information of 20 samples of 10 kinds of plants was obtained with high-performance liquid chromatographic method and classification based on their chemical information was made through Hierarchical cluster. Flavonoids and saponins were the main components of the C. chinensis plants. We did the high-performance liquid chromatography from the flavonoids and saponins side respectively.
  
  
  RESULTS
  Expected results were achieved in the Hierarchical clusters of the chromatographic data of the plants of genus C. chinensis which supplied the foundation for studying crude drugs categorys and those close of C. chinensis.
  
  
  CONCLUSIONS
  The cluster and identification results show the method is acceptable, simple, rapid, inexpensive and repeatable.
