我们在工作中曾遇到基层送检注射器内残留的微量链霉素药液,要求检查是否污染有青霉素。为了寻找在大量其它抗菌素存在下检出微量青霉素检查的方法,本文参考文献方法[Manni PE et al: J Chromatog 76(2): 512, 1973; Larel Macek: Pharmaceutical Applications of Thin-Layer and Paper Chromatography, p661, Elsevier Publishing Company, 1972]采用薄层层析.对临床常用的硫酸链霉素、硫酸卡那霉素和硫酸庆大霉素中污染微量青霉素的检查方法进行了实验探讨,取得较
We have encountered at the grass-roots level delivery of trace drug residues in the syringe streptomycin liquid, asked to check whether the penicillin contamination. In order to search for a method for the detection of trace penicillin in the presence of a large number of other antibiotics, reference is made to the literature method [Manni PE et al: J Chromatog 76 (2): 512, 1973; Larel Macek: Pharmaceutical Applications of Thin-Layer and Paper Chromatography, p661, Elsevier Publishing Company, 1972] using thin-layer chromatography on the clinical commonly used streptomycin sulfate, kanamycin sulfate and gentamicin contamination of trace penicillin testing methods were explored to obtain more
