ABSTRACT
<p><b>OBJECTIVE</b>To develop a capillary electrophoresis system for enantiomeric impurity test of repaglinide.</p><p><b>METHODS</b>An uncoated fused silica capillary (50 μm×50 cm, with an effective length of 41 cm) was used. The running buffer was composed of 30 mmol/L NaH2PO4 and 5 mg/ml carboxymethyl-β-cyclodextrin(pH 3.5).</p><p><b>RESULTS</b>Linear range was 2.00-80.00 μg/ml (correlation coefficient was 0.9993). The average recovery rate was 92.5% to 105.0%.</p><p><b>CONCLUSION</b>The method is simple, accurate and sensitive and it can be used for determination of enantiomeric impurities in repaglinide tablet.</p>
