建立了气相色谱法定量分析牙膏中薄荷醇含量来鉴别牙膏种类的方法。以正十四烷作为内标，采用DB-FFAP毛细管柱分离样品，氢火焰离子化检测器（FID）测定牙膏中薄荷醇的含量。线性方程为Y＝1.1137C-0.0087，相关系数r＝0.9991，线性范围为0.01～0.20 mg/mL，最低检测浓度为2.61μg/mL，平均回收率为94.3％，相对标准偏差1.66％。该方法具有操作简便，灵敏、准确、重现性好等特点，适用于公安基层办案工作的需要。

A new method of identifying the toothpaste samples was established by determining the content of menthol in toothpaste samples by gas chromatography.N-tetradecane was added in and GC analysis of the eluate , prior to GC analysis.The GC analysis was carried out by DB -FFAP capillary column and flame ionization detector ( FID).The linear equation was Y =1.1137C -0.0087, with r =0.9991.The linear range was 0.01 ~0.20 mg/mL and the limit of detection was 2.61 μg/mL.The average recoveries were 94.3%and RSD=1.66%.The method was simple , rapid and sensitive.A useful method for determining menthol in toothpaste samples was provided for chemical analysis.
