| Abstract: | Objective To establish a HPLC method for determination of riboflavin sodium phosphate for injection. Methods HPLC was used to determine directly riboflavin sodium phosphate for injection on C18 column with the mobile phase of CH3 CN-0. 025 mol/L potassium dihydrogen phosphate solution （20： 80） at a flow rate of 1.0 mL/min and column temperature was 25℃. The detection wavelength was set at 267 nm. Results The calibration curve was linear in range of 4. 01 - 100 μg/mL （r = 0. 9999）. The limit of detection for the assay was 2 ng. The average recovery of the added sample was 99.86% and RSD was 0. 19%. Conclusion The method is quick, accurate, and has strong specificity and good reproducibility. It provides a good way for the quality control of riboflavin sodium phosphate for injection. |
