摘要
目的建立麝香镇痛膏中樟脑含量的气相色谱方法。方法以挥发油测定器蒸馏制备供试液，以萘为内标物，PEG-20M为固定项的毛细管柱，氮气作为载气，FLD检测器，采用程序升温，内标法测定含量。结果樟脑在浓度为0．5055—5．055g·L^-1范围内呈良好的线性关系（r=0．9995），平均回收率为97．04％，RSD=1．47％。结论该方法简便、准确、分离度好，可用于控制麝香镇痛膏的质量。
Aim To build the method of determining camphor in shexiang zhentong plaster by GC. Method The sample solution was distilled in volatile oil determination apparatus. Naphthalene was used for the internal standard. The GC system consisted of capillary col- umn, PEG- 20M as the stationary phase, nitrogen as the carrier gas. With FLD as the detector,the programmed temperature-GC and internal standard method were employed to determine the components in Shexiang Zhentong plaster. Result Camphor showed a good linear relationship in the concentration range of 0. 5055 - 5. 055 g · L^ -1 （ r =0. 9 995 ）, and the average recovery was 97.04%. RSD was 1. 47%. Conclusion The method is simple,accurate and separable,and can be used to control the quality of Shexiang Zhentong plaster.
