Objective:
To identify Cassia seeds of six species by capillary electrophoresis.
Method:
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.
Result:
Four common peaks could be found in the electropherograms of six species Cassia seeds, and the characteristic peaks could also be observed.
Conclusion:
Fingerprints of the six species of Cassia seeds show significant differences, which can be used for their identification.
