ABSTRACT Objective:To establish a HPLC method for determination the content of cefoxitin sodium for injection。Method:The Bon chrom C18 column(150 mm×4.6mm,5μm)was used。 The mobile phase consisted of water-acetonitrile-glacial acetic acid(810:190:10), the flow rate was 1ml·min-1;the detection wavelength was at 254 nm。Result:The cefoxitin sodium presented a good linear correlation within a rrange of 75 - 1200μg·ml-1,r=0.999 9。The average recovery was 100.0%,RSD=0.1%。Conclusion:This mothed is simple,rapid and accurate。
KEY WORDS Cefoxitin sodium;HPLC;Content determination
