建立了毛细管气相色谱法同时测定祖师麻关节止痛膏中的樟脑、薄荷脑、冰片和水杨酸甲酯。以正辛醇为内标,用挥发油测定器蒸馏制备供试品溶液,采用PEG-20M石英毛细管柱,氢火焰离子检测器。樟脑、薄荷脑、冰片和水杨酸甲酯分别在30～480、35～560、33～520和30～472μg/ml浓度范围内线性关系良好,回收率分别为99.2%、99.1%、99.1%和99.0%,RSD分别为0.8%、0.7%、0.9%和1.1%。
A capillary gas chromatography method was established for the simultaneous determination of camphor, menthol, borneol and methyl salicylate in Jiezhitongjiejie cream. With n-octanol as internal standard, volatile oil analyzer for the preparation of the test solution was distilled, using a PEG-20M quartz capillary column, flame ionization detector. The linear relationship was found between camphor, menthol, borneol and methyl salicylate in the range of 30 ~ 480, 35 ~ 560, 33 ~ 520 and 30 ~ 472μg / ml respectively.The recoveries were 99.2%, 99.1%, 99.1% And 99.0% with RSDs of 0.8%, 0.7%, 0.9% and 1.1%, respectively.
