  • Objective : To develop a method for purity test and enantioseparation of ephedrine levorotatory by capillary electrophoresis(CE). Methods : The cyclodextrin,concentration,pH,organic solvent were studied,and the results indicated that the enantiomer of ephedrin and ephedrine levorotatory were baseline separated under the following experimental conditions:uncoated fused silica capillary(75 μm × 68 cm),25 mmol/L Tris,2% HP-β-CD and 1% SBE-β-CD,pH was adjusted at 3.0 by phosphoric acid,and 15 kV separation voltage.The detection wavelength was set at 214 nm with the column temperature of 15 ℃. Results : Under the experimental conditions adopted,the baseline separation of ephedrin and ephedrine levorotatory was obtained. Conclusions : The proposed method is simple,reliable and can be used for routine purity test and chiral separation.
