This paper describes a sensitive high-performance liquid chromatographic method for the quantitative determination of alpha-keto acids in plasma using a fluorescence detector. This method is about ten times more sensitive than that reported in a previous paper. Only 50 microliters of plasma are needed for the determination of alpha-keto acids. However, p-hydroxyphenylpyruvic acid could not be analysed because the quinoxalinol derived from it does not exhibit fluorescence.
本文描述了一种使用荧光检测器定量测定血浆中α-酮酸的灵敏高效液相色谱法。该方法的灵敏度比之前一篇论文报道的方法高约十倍。测定α-酮酸仅需50微升血浆。然而，对羟基苯丙酮酸无法进行分析，因为由其衍生的喹喔啉醇不显示荧光。
