Abstract: Objective:To establisha method for determination of tofatib citrate tablets and validate the methodology. Three batches of tofatib citrate tablets were tested.Methods:Separation was carried out using C18with mobile phase of acetonitrile and 0.03 mol·L-1 potassium dihydrogen phosphate(75∶25). The flow rate was 1.0 mL·min-1and the column temperature was 30 ℃.The detection wavelength was at 287 nm.Results: The results showed that thespecificity, detection limit and quantitative limit, linearity and range, accuracy and precision of the test method meet the requirements of laws and regulations. Conclusion: The method can be used to determine the content of tofatib citrate tablets. It has the advantages of simple operation, accurate results, strong specificity and high stability. It has a good application prospect.
