A simple, sensitive and specific method for the determination of kynurenine is described. This is based on alkaline cleavage of kynurenine, followed by solvent extraction, trifluoroacetylation and gas--liquid chromatography with electron capture detection. Using this method kynurenine has been determined in urine and plasma, and for the first time in brain and cerebrospinal fluid. Increases in kynurenine in brain, plasma and urine are demonstrated following tryptophan administration to man and rat.
本文描述了一种测定犬尿氨酸的简单、灵敏且特异的方法。该方法基于犬尿氨酸的碱性裂解,随后进行溶剂萃取、三氟乙酰化以及带电子捕获检测的气液色谱分析。使用此方法已测定了尿液和血浆中的犬尿氨酸,并且首次测定了脑和脑脊液中的犬尿氨酸。对人和大鼠给予色氨酸后,脑、血浆和尿液中的犬尿氨酸均有所增加。
