摘要(Abstract):

目的以2-甲基-β-环糊精(2-O-methylated-β-cyclodextrin,2-O-M-β-CD)为手性添加剂,利用毛细管电泳法(capillary electrophoresis,CE)对消旋体药物甲溴后马托品、氧氟沙星、酮康唑、利阿唑和卡维地洛进行拆分研究。方法考察了背景电解质溶液的pH值、2-O-M-β-CD浓度、缓冲盐浓度对分离的影响,优化了分离条件。结果在最佳分离条件下,甲溴后马托品、氧氟沙星、酮康唑、利阿唑对映体达到完全分离,分离度分别为3.6、2.8、1.7、1.5;卡维地洛对映体分离度达到1.4。结论所建立的毛细管电泳法适于除卡维地洛外其余4种药物的对映体分离。
Objective To establish a capillary electrophoresis(CE)method for separating homatropine methyl bromide,ofloxacin,ketoconazole,liarozole and carvedilol.Methods 2-O-methylated-β-cyclodextrin(2-O-M-β-CD)was used as a chiral selector.The influence of buffer pH,2-O-M-β-CD concentration,buffer concentration on separation was investigated.Results Under the conditions tested,homatropine methylbromide,ofloxacin,ketoconazole,liarozole,carvedilol were separated with the maximum resolution factors of 3.6,2.8,1.7,1.5,1.4,respectively.Conclusions This CE method for separating enantiomers has advantages of the short analysis time,good reproducibility and high sensitivity.
