【Abstract】 Objective To establish HPLC method for determination of doxiflurid in e content and its related substances.Methods The column was Diamonsil-C18 colum n (250 mm×4.6 mm,5 μm).The mobile phase was acetonitrile-water (1 ∶1).The detection wavelength was 269 nm.The flow rate was 0.8 mL/min.Results There was a good linear relationship with the range of 10.0-200.0 μg/mL for determinati on of the doxifluridine’s content,r=0.999 9(n=5).The average recovery rate was 100.2%,RSD=0.14%.Conclusion The method i... 更多还原 【关键词】 去氧氟尿苷; 含量测定; 有关物质; 高效液相色谱法; 【Key words】 doxifluridine; content determination; related substances; HPLC;
