Abstract

A rapid, simple, and accurate method for the determination of kanamycin and dibekacin in serum by use of high-pressure liquid chromatography is described. The serum proteins were precipitated with 3.5% perchloric acid containing sodium octanesulfonate. After centrifugation, a sample of the supernatant was directly injected into the chromatograph. The determination of kanamycin and dibekacin was performed by a combination of reverse-phase, ion-pair chromatography, postcolumn derivatization with o-phthalaldehyde, and fluorescence detection. The correlation coefficients with fluorescence polarization immunoassay were 0.996 for kanamycin and 0.957 for dibekacin.

摘要

描述了一种使用高压液相色谱法快速、简单且准确地测定血清中卡那霉素和地贝卡星的方法。血清蛋白用含辛烷磺酸钠的3.5%高氯酸沉淀。离心后,将上清液样品直接注入色谱仪。卡那霉素和地贝卡星的测定采用反相、离子对色谱法、邻苯二甲醛柱后衍生化和荧光检测相结合的方法。与荧光偏振免疫测定法的相关系数,卡那霉素为0.996,地贝卡星为0.957。
