| Abstract: | OBJECTIVE：To establish the method for the content determination of ceftazidime t-butyl ester in Ceftazidime and its preparation.METHODS：HPLC was adopted.Samples were determined on C 18 column with acetonitrile-pH 7.0 phosphate buffer solution（7∶93）as mobile phase A and acetonitrile-pH 7.0 phosphate buffer solution（25∶75）as mobile phase B（gradient elution）. UV detection wavelength was set at 255 nm.RESULTS：The linear range of ceftazidime t-butyl ester was 0.01～1.22μg·μL -1 with an average recovery of 99.4%（RSD=1.0%）.CONCLUSION：The method is specific,rapid and accurate for the content determnnation of ceftazidime t-butyl ester in Ceftazidime and its preparation. |
