| 目的建立琥珀酸多西拉敏原料中 8种有机溶剂残留量的测定方法。方法采用毛细管气相色谱法，色谱柱为 ZB- WAX Plus毛细管柱(以聚乙二醇为固定相)，配备 FID检测器，程序升温，载气为氮气， 70%二甲基亚砜为溶剂，以外标法定量检测琥珀酸多西拉敏原料药中的甲基叔丁基醚、四氢呋喃、乙酸乙酯、异丙醇、乙苯、对二甲苯、间二甲苯和邻二甲苯的残留量。结果在所建立的色谱条件下， 8种有机溶剂完全分离，在所考察的浓度范围内具有良好线性， r为 0.999 0～0.999 5，平均回收率 99.1%～101.6%，精密度相对标准偏差( RSD)均小于 10%。结论本方法操作简便，能够准确测定琥珀酸多西拉敏的有机溶剂残留量。 |

| Objective To establish a method for determination of the eight residual organic solvents in doxylamine succinate. Methods The contents of methyl tert-butyl ether，tetrahydrofuran，ethyl acetate，isopropanol，ethylbenzene，p-xylene，m-xylene ando-xylene in doxylamine succinate were quantitatively detected by external standard method.The capillary gas chromatography wasperformed on a ZB-WAX Plus(polyethyleneglycol as the stationary phase)capillary column，with FID detector，temperature pro- grammed，with nitrogen as carrier gas and 70% DMSO as solvent.Results Under the established chromatographic conditions，the eight residual organic solvents of doxylamine succinate were separated efficiently by GC，with good the linearity within the observed concentration range，and the regression coefficient were in the range from 0.999 0 to 0.999 5，respectively，while the recoveries were in the range from 99.1% to 101.6%，and the RSD of precision were all less than 10%.Conclusion This method is simple， and it can be used to accurately determinate the residual organic solvents contend in doxylamine succinate. |
