摘要：

运用毛细管电色谱（pCEC）模式，以羟丙基-β-环糊精（HP-β-CD）作为手性选择剂，对1-甲基-3-苯基丙胺对映体进行手性分离。1-甲基-3-苯基丙胺对映体在最佳的条件下如：手性选择剂浓度10 g/L、流动相配比：V(乙腈)∶V(磷酸盐体系)=60∶40溶液(5 mmol/L）、背景电解质pH=7.6、柱温16 ℃和分离电压10 kV达到了基线分离,该方法重现性好、简便、快捷。

Abstract:

1-Dimethyl-3-phenylpropylamine enantiomer was separated with hydroxypropyl-β-cyclodextrin（HP-β-CD） as chiral selector by means of pressurized capillary electrochromatography(pCEC). The optimal experimental conditions are HP-β-CD concentration 10 g/L, background buffer pH=7.6, capillary temperature 16 ℃, voltage 10 kV, and the mobile phase consisted of a solution of acetonitrile and phosphate at a volume ratio of V(CH3CN)∶V(NaH2PO4-Na2HPO4)=60∶40. The method is simple, rapid and the reproducibility is good.

Key words: pressurized capillary electrochromatography(pCEC),dimethylphenylpropylamine,enantiomer separation,hydroxypropyl-β-cyclodextrin
