摘要
研究了硝酸介质酪氨酸与α-显色剂的显色反应体系。显色产物在 52 0nm处有最大吸收 ,表观摩尔吸光系数为 6.1 9× 1 0 3L· mol- 1· cm- 1。酪氨酸含量在 0 .0 2～ 0 .1 6μmol/m L 范围内符合比尔定律 ,该法可用于人尿中酪氨酸的测定。
A new method for determination of tyrosine based on reaction of tyrosine with α reagent in nitric acid was proposed. The apparent molar absorptivity of the product is 6.19×10 3L/(mol·cm) at 520 nm. The Beer's law was obeyed in the range of 0.02～0 16 μmol/mL. This method was applied to the determination of tyrosine in human urine.
