摘　　要：目的 :建立维C银翘片 (维生素C ,对乙酰氨基酚 ,金银花 ,等 )中对乙酰氨基酚含量的检测方法。方法 :采用中红外漫反射定量分析技术 ,测定了维C银翘片中对乙酰氨基酚的含量。结果 :可直接测定出样品中对乙酰氨基酚的含量 ,且吸光度与对乙酰氨基酚的浓度成良好的线性关系 ,平均回收率为 98.4 0 % ,RSD为 3.18%。结论 :本方法简便、准确、可靠 。Objective: To establish a method for determination of paracetamol in Vc Yinqiao tablets (Vc, paracetamol, Flos lonicerae, Fructus Forsythies), etc. Methods: Diffuse Relectance FTIR was used to determinate paracetamol in the Vc Yinqiao tablets. Results: The content of paracetamol could be obtained directly, and the relationship between the absorbance and the concentration was linear. The average recovery of paracetamol was 98.40, and RSD was 3.18%. Conclusion: The method is simple, fast and reliable. It has been proved to be a good practice for determination of Vitamin C in the Vc Yinqiao Tablets.
