title: [Pharmacognostical study on seven species from Astragalus genus in Yunnan].
abstract: OBJECTIVE
  For the identification and utilization of the Astragalus plants from Yunnan, pharmacognostical studies were systematically performed for seven Astragalus plants which were selected from four subgenera of Astragalus genus.
  
  
  METHODS
  Standard pharmacognosy methods and HPLC method were adopted, and microscopic characteristics and major chemical constituents of the test plant samples were compared.
  
  
  RESULTS
  There were differences in root transverse section, powder and chemical constituents of the seven Astragalus plants.
  
  
  CONCLUSIONS
  This study can provide the pharmacognosy experimental basis for the future study of Astragalus plants.
