摘要
目的建立气相色谱法测定安徽地产薄荷中薄荷脑的含量。方法采用气相色谱法,色谱柱为聚乙二醇-20m毛细管柱30m×0.53mm×0.25μm,柱温:120℃;进样口:220℃,分流比10∶1;FID检测器。结果薄荷脑在0.0341mg·m L-1~0.682mg·m L-1范围内呈线性关系,线性方程为y=3051.7793x+7.9986,r=0.9999(n=6);平均回收率分别为101.7%,RSD为2.7%。结论本方法简便、准确、快速,可用于安徽地产薄荷的质量控制。
OBJECTIVE To establish an GC method for the determination menthol in Mentha of AnHui prov- ince. METHODS The PEG-20m capillary column （30m ×0. 53mm×0. 25μm） was used with FID,nitrogen as the cartier gas,column temperature at 120℃, and with the split flow ratio being 10： 1, the injector temperature 220℃. RESULTS The menthol sample showed a good linear relationship at the range of 0. 0341- 0. 682mg· mL-1 （ r = 0. 9999,n =6）. The average recovery rate was 101.7% and RSD was 2. 7%. CONCLUSION This method is sim- ple, rapid and accurate, which is suitable for the quality control of Mentha.
