摘要:目的建立一种用气相色谱法同时测定止痒搽剂中樟脑、薄荷脑、冰片三组分含量的方法。方法采用聚乙二醇(PEG)-20M填充柱 (涂布浓度为10%);柱温155℃;进样口温度为190℃;FID检测器,检测器温度250℃。结果樟脑在0.198~1.191 mg/ml范围内呈良好线性关系(r=0.999 99),薄荷脑在0.132~0.790 mg/ml范围内呈良好线性关系(r=0.999 99),冰片在0.139~0.833 mg/ml范围内呈良好线性关系(r=0.999 9);平均加样回收率分别为:樟脑95.21%,RSD为1.58%(n=9),薄荷脑 102.71%,RSD为1.29%(n=9) ,冰片99.33%,RSD为1.40%(n=9)。结论该法简便快速,结果准确,可以有效地控制该药品的质量。关键词:气相色谱法; 止痒搽剂; 樟脑; 薄荷脑; 冰片

Abstract:ObjectiveTo estabilsh a method for simultaneous determination of camphor, menthol, and borneol in antipruritic liniment by GC. MethodsUsing 10% PEG-20M packed column .The column temperature was at 155℃. Injector temperature was at 190℃. FID detector with temperature at 250℃. ResultsCamphor showed a good linear relationship at a range of 0.198~1.191 mg/ml(r=0.999 99) ......
