Abstract

An accurate and sensitive method was developed for the complete separation of the native tetrapyrroles, such as bilirubin and its mono- and di-conjugates of glucuronic acid, glucose and xylose, by ion-pair reversed-phase high-pressure liquid chromatography. The application of this method was demonstrated by the analysis of bile pigments in human bile and urine, and the method also makes it possible to estimate very low UDP-glucuronyltransferase activity, such as is found in the human foetal and neonatal liver.

摘要

通过离子对反相高压液相色谱法,开发了一种准确且灵敏的方法,用于完全分离天然四吡咯,如胆红素及其葡萄糖醛酸、葡萄糖和木糖的单共轭物和双共轭物。通过分析人胆汁和尿液中的胆汁色素证明了该方法的应用,并且该方法还能够估计极低的尿苷二磷酸葡萄糖醛酸基转移酶活性,如在人胎儿和新生儿肝脏中发现的那样。
