消曚眼膏中樟脑的含量测定

GC Determination and Identification of Camphor in Xiaomeng Eye Ointment

目的：建立GC法测定消嚎眼膏中冰片掺假物一樟脑的含量。方法：采用DB－WAX色谱柱（柱长30m，内径0．53mm，膜厚度1μm），载气为氮气，分流比为10：1，柱温为140℃，进样口温度为180℃，检测器温度为200℃。结果：樟脑在0．00499～0．9981μg范围内线性关系良好（r=0．9997），回收率为99．09％（n=9），RSD为1．62％。结论：本法灵敏、准确，可作为该产品的质量控制指标。

Objective： To establish GC method for determination of camphor in Xiaomeng eye ointment. Methods：The DB-WAX chromatographic column （30m×0.53mm×1μm）was adopted with nitrogen as the carrier gas and the split ratio of 10：1.The column temperature was 140℃ ,the injection port temperature was 180℃ and the detector temperature was 200℃. Results ：The linear range of camphor was in the range of 0.00499～0.998μg（r=0.9997）, and the average recovery（n=9）was 99.09% and RSD was 1.62%.Conclusion： This method is convenient, rapid, accurate and reproducible, and can be used for quality control of Xiaomeng eye ointment.
