摘　　要：目的 建立麝香草酚含量的气相色谱测定法。方法 色谱条件为DB-I石英毛细管色谱柱，程序升温，起始温度80％，保持4min，以15℃·min^-1的速率升至120℃，保持6min，FID检测器，内标物为水杨酸甲酯。结果 麝香草酚在0．1506-0．3514g·L^-1的浓度范围内线性关系良好（r=0．9991），加样平均回收率为98．34％，RSD=1．77％（n=6）。结论 该方法处理简单、分离效果好，结果准确可靠。Aim To establish a method to determine the content of Thymol in Zhiyang xiaoyan water. Methods A DB-I capillary column is used to separate the samples. And methyl salicylate is the internal standard. Temperature programming started at 80℃, holding for 4 minutes, then increased to 120℃ at a rate of 15℃·min^-1 , holding 6 minutes. The FID was used as a detector. Results The linear range for thymol was 0.1506 - 0.3514 g · L^-1 （ r = 0. 9991 ）. The average recovery was 98.34% （ RSD = 1.75% , n = 6 ）. Conclusion The method is simple,reliable and can be used for the content determination and the quality control of thymol.
