摘要
目的 :建立气相色谱法测定经不痛巴布膏中丁香酚的含量。方法 :气相色谱法 ,采用PEG 2 0M石英毛细管柱 ,柱温1 60°C ,FID检测器检测温度 2 30°C。结果 :丁香酚在 0 .38μg～ 6 .1 4 μg范围内呈良好线性关系 ,r=0 .9993。平均回收率为 98.66 % ,RSD为 2 .1 8%。结论 :方法简便准确 ,重复性好 。
Objective:To establish a GC method for the determination of eugenol in Jingbutong Babugao. Methods: The determination was carried out on a PEG 20M capillary column with temperature at 160 °C , FID detector with temperature at 230 °C . Results: The eugenol sample showed a good linear relationship at the range of 0.38～6.14μg and correlation coefficient was 0.9993. The average recovery was 98.60% with a RSD of 2.18%. Conclusion: The method is simple, accurate, reproducible and can be used for determination of eugenol in Jingbutong Babugao.
