沒有上藥典的呢 Objective To establish an HPLC method for determining the content of febuxostat and its related substances.Methods The determination of febuxostat and the separation of its related substances was performed on a C18 column(200 mm ×4.6 mm,5 μm).The mobile phase was methanol-acetonitrile-0.05%(φ)phosphoric acid(V∶V∶V=24∶46∶30).The flow rate was 1.0 mL·min^-1.Ultraviolet absorption detector was set at 315 nm and column temperature was 35 ℃.Results The linear range of febuxostat was between 15.7 and 94.3 mg·L^-1(r=0.999 8).The average recovery was 100.5%with RSD of 1.0%.The related substances of febuxostat could be completely separated from febuxostat.The limit of detection(LOD)was 0.5 ng.Conclusions The method is simple and accurate for quality control of the febuxostat. |
