摘要
Aim To establish a capillary electrophoresis method for enantiomericseparation of meptazinol hydrochlo-ride. Methods The separation conditions such ascyclodextrin(CD)type, buffer pH, concentration of 2,3,6-O-trimethyl-β-cyclodextrin and organicadditives were optimized. An optimum concentration was 30 mmol· L^(-1) phosphate (pH 7.02) with 10%(W/V) TM-β-CD and 2% acetonitrile. Results Baseline resolution of the enantiomer was readilyachieved using 2, 3, 6-O-trimethyl-β-cyclodextrin. Conclusion This is a convenient method for fastenantiomeric resolution of meptazinol hydrochloride.
