Determination of Content of Ceftizoxime by RP-HPLC / 中国药房

ABSTRACT

OBJECTIVE:To determine the content of ceftizoxime for injection METHODS:A RP-HPLC method was established,the polarls C18 was used as analysis column The mobile phase consisted of 0 23% sodium hydrogen phosphate and 0 14% trisodium buffer-acetonitrile(85∶15),the flow rate was 1 0ml/min,the detection wavelength was 254nm RESULTS:The linear range of ceftizoxime was 4 1 462～37 3 156?g/ml,r=0 9 999 The relative standard deviation was 0 6% CONCL_USIONThe method is rapid,accurate and suitable for determination of content of ceftizoxime for injection
