Objective: To establish a HPLC for determination of paracetamol and vitamin C in Wei C Yinqao Tablets. Methods: A Hypersil C 18 column(4.6×250mm,5μm) was used with a mobile phase of 0.02mol/L potassium dihydrogen phosphate acetonitrile (90∶10). The detection wavelength was 249nm. Results: The average recoveries of paracetamol and vitamin C were 100.5%(RSD was 1.33) and 98.7%(RSD was 1.68%), respectively. Conclusion: The method is simple, rapid and accurate. It can be used for quantitative analysis of Wei C Yinqiao Tablets.
