title: [Identification of six species of Cassia seeds by capillary electrophoresis].
abstract: OBJECTIVE
  To identify Cassia seeds of six species by capillary electrophoresis.
  
  
  METHODS
  The water-soluble extracts of Cassia seeds of six species were analyzed by capillary electrophoresis. The running buffer was 0.1 mol.L-1 borate, 0.1 mol.L-1 SDS, pH 8.5. The separation voltage was 25 kV.
  
  
  RESULTS
  Four common peaks could be found in the electropherograms of six species Cassia seeds, and the characteristic peaks could also be observed.
  
  
  CONCLUSIONS
  Fingerprints of the six species of Cassia seeds show significant differences, which can be used for their identification.
