目的 :研究丁香和小儿健胃灵口服液中丁香酚的定量方法。方法 :样品用乙醚提取 ,以PEG - 2 0M为气相色谱柱 ,柱温为 135℃ ,桂皮醛为内标物 ,FID检测器 ,测定丁香药材和小儿健胃灵口服液中丁香酚的含量。结果 :丁香酚在 0 .2～ 1.0 μg范围间呈良好线性关系 ,平均回收率为 96 .5 3% ,RSD =2 .2 5 %。结论 :本方法简便、快速、准确、重现性好 ,可作为本制剂的质量控制方法。
Objective: To study the quantitative method of eugenol in clove and children’s Weibing oral liquid. Methods: The samples were extracted with ether. The content of eugenol in clove herbs and pediatric jingweiningling oral liquid was determined by PEG - 20M column, column temperature 135 ℃, cinnamaldehyde as internal standard and FID detector. Results: The eugenol showed a good linear relationship in the range of 0.2-2.0 μg with an average recovery of 96.53% and RSD of 2.55%. Conclusion: The method is simple, rapid, accurate and reproducible. It can be used as quality control method of this preparation.
