Abstract:
OBJECTIVETo identify Cassia seeds of six species by capillary electrophoresis.
METHODThe 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.
RESULTFour common peaks could be found in the electropherograms of six species Cassia seeds, and the characteristic peaks could also be observed.
CONCLUSIONFingerprints of the six species of Cassia seeds show significant differences, which can be used for their identification.
