Abstract:Objective:To establish test method for Caffeine contents in Compound Paracetamol Tablets. Methods: HPLC. The chromatographic column is Agilent C18 column (250mm×4.6mm,5μm) ; the mobile phase is Methanol Water (40: 60) while the flow rate is 1.0 mL/min with column temperature of 40℃ at wavelength of 216rim. Results : The Average Recovery Rate is 99.4 % ; the Relative Standard Deviation (RSD) is 0.8;; the linear range of Caffeine is 30.04--1502ng, and the system accuracy is 0.8%. Conclusion:It is available to control the quality of Compound Paracetamol Tablets by applying HPLC to determine the content of Caffeine.
Keywords:HPLC  Compound Paracetamol Tablets  Caffeine  Content
