摘要
目的:建立毛细管气相色谱法同时测定红药贴膏中樟脑、薄荷脑、冰片和水杨酸甲酯的含量。方法:采用毛细管气相色谱法。色谱柱为PEG-20M石英毛细管柱(0.25 mm×0.25μm×30 m),氢火焰离子检测器,检测器和气化室的温度均为200℃,柱温160℃,氮气为载气,正辛醇为内标物,用挥发油测定器蒸馏制备供试品溶液。结果:在该色谱条件下,樟脑、薄荷脑、冰片和水杨酸甲酯分离度和线性关系良好,回收率分别为99.8%,100.3%,99.5%,99.7%。结论:该方法简便、准确、专属性强、重复性好,可用于红药贴膏的质量控制。
Objective: To establish a method for determination of camphor,menthol,borneol and methylsalicylate in Hongyao strapping.Method:Capillary gas chromatography was adopted.The chromatography separation was carried out with PEG-20M capillary column(0.25 μm × 0.25 mm × 30 m),using a flame ionization detector.The injector and detector temperature were set at 200 ℃.The column temperature was 160 ℃.n-Octanol was used as internal standard.The sample solution was prepared by distillation with essential oil collector.Result: The resolution and linearity of camphor,menthol,borneol and methylsalicylate were good under the chromatographic conditions.The average recoveries of camphor,menthol,borneol and methylsalicylate were 99.8%,100.3%,99.5%,99.7%.Conclusion:This method is simple,sensitive,accurate and has good repeatability for controlling the quality of camphor,menthol,borneol and methylsalicylate in Hongyao strapping.
