高效液相色谱法测定舒普深中的舒巴坦钠和头孢哌酮钠

 应用反相高效液相色谱外标定量法同时测定了舒普深中的舒巴坦钠和头孢哌酮钠。采用 pH 4 0的磷酸水溶液 乙腈 (体积比为 80∶2 0 )组成的流动相 ,在ODS柱上 ,于 12min内同时测定舒巴坦钠和头孢哌酮钠。方法简单 ,重现性好 ,在线性范围内舒巴坦钠的相关系数为 0 9997(n =5 ) ,头孢哌酮钠的相关系数为 0 9991(n=5 )。方法适于对药品舒普深的生产过程及临床上该药的血药浓度的监测。

Simultaneous Determination of Sulbactam Sodium and Cefoperazone Sodium in Sulperazon by High Performance Liquid Chromatography

A reversed-phase, isocratic high performance liquid chromatographic method with acid mobile phase can separate sulbactam and cafoperazone within 12 minutes. Column packed with Hypersil ODS2(250 mm x 4.6 mm i.d., 5 microns) was manufactured by Dalian Elite Company. Mobile phase is composed of water (adjusted to pH 4.0 with 1% phosphoric acid) and acetonitrile (80:20, V/V). The detection was performed at 210 nm and the injection volume was 2 microL. Cefoperazone and sulbactam have good linearity in the ranges of 100 mg/L to 800 mg/L and 100 mg/L to 1,000 mg/L with the correlation coefficients of 0.9991 and 0.9997 respectively. This method is easily to be operated and can be applied for manufacturing and medicinal study.
