目的：建立 GC法测定甘油止痒洗剂中苯酚和薄荷脑的含量方法。方法：色谱柱为 Zebron ZB-Wax(0.32 mm ×30.0 m,0.50μm)毛细管柱色谱柱；FID检测器；柱温为60℃,保持1 min,然后以8℃·min-1速率升温至160℃,保温10 min,进样口温度180℃,检测器温度300℃。载气为氮气。结果：苯酚和薄荷脑的线性范围分别是0.5~10.0 mg · ml-1( r =0.9999)和0.25~5.0 mg·ml-1(r=0.9999)。苯酚和薄荷脑的平均回收率分别为99.01%(RSD=0.90%,n=9)和99.70%(RSD=0.98%,n=9)。结论：该方法简单,结果准确可靠,可用于止痒洗剂中苯酚和薄荷脑的含量测定。

Objective:To establish a GC method for the determination of phenol and L-menthol in glycerin Zhiyang lotions. Meth-ods:A Zebron ZB-WAX(0. 32 mm × 30. 0 m,0. 50 μm) capillary column was used with an FID detector. The column temperature was 60℃, maintained for 1 min, and then raised to 160℃ at the rate of 8℃·min-1 , and maintained 10 minutes. The inlet tempera-ture was 180℃, the detector temperature was 300℃, and the carrier gas was nitrogen. Results:The linear range of phenol and L-men-thol was 0. 5-10. 0 mg·ml-1(r=0. 999 9) and 0. 25-5. 0 mg·ml-1(r=0. 999 9), respectively. The average recovery of phenol and L-menthol was 99. 01%(RSD=0. 90%,n=9)and 99. 70%(RSD=0. 98%,n=9), respectively. Conclusion: The method is sim-ple, accurate and reliable, and can be used to determine the concentration of phenol and L-menthol in glycerin Zhiyang lotions.
