摘要
目的建立了用毛细管电泳分离和测定摇头丸中的甲基安非他明和咖啡因的方法。方法观察缓冲液的种类以及缓冲液的pH值对分离的影响。结果在10～800mg/L的范围内,用Na2HPO4-Na2B4O7和NaH2PO4-Na2HPO4缓冲液,在pH7.0～9.5时,两种药物成分均有较好的线性(r>0.99),三种摇头丸中的甲基安非他明和咖啡因的含量随浓度的增加其回收率增加。结论该分析方法速度快,重现性好,检测结果准确。
Methamphetamine and caffeine in illicit drug were separated and determined by using capillary zone electrophoresis.The influence of buffer system and pH of the running buffer were investigated.Regression equations revealed linear relationships(correlation coefficients:0.9938～0.9989)between the ratios of peak areas of internal standard and its concentration.The relative standard deviations of the migration time are between0.022%～0.038%.
