Identification of six species of Cassia seeds by capillary electrophoresis / 中国中药杂志

<p><b>OBJECTIVE</b>To identify Cassia seeds of six species by capillary electrophoresis.</p><p><b>METHOD</b>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.</p><p><b>RESULT</b>Four common peaks could be found in the electropherograms of six species Cassia seeds, and the characteristic peaks could also be observed.</p><p><b>CONCLUSION</b>Fingerprints of the six species of Cassia seeds show significant differences, which can be used for their identification.</p>
