Abstract

A gas chromatographic method for the determination of di- and polyamines in human urine has been developed. The di- and polyamines have been extracted from standard solutions or from urine by a butanolic method modified to improve its sensitivity in relation to the low concentration of the amines in human normal urine. The quantitation is controlled by using two internal standards: 1,6-diaminohexane for Putrescine and Cadaverine, l-ephedrine for Spermidine and Spermine. Distilled water was the final solvent injected into the GLC column and the detector response was linear between 5 and 100 ng.

摘要

已开发出一种用于测定人尿中二胺和多胺的气相色谱法。通过改进丁醇法从标准溶液或尿液中提取二胺和多胺,以提高其对人正常尿液中低浓度胺类的灵敏度。使用两种内标物进行定量:用于腐胺和尸胺的1,6 - 二氨基己烷,用于亚精胺和精胺的L - 麻黄碱。蒸馏水是注入气相色谱柱的最终溶剂,检测器响应在5至100 ng之间呈线性。
