Determination of paracetamol in the Vc Yinqiao Tablets by diffuse reflectance FTIR / 中成药

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.
