【摘要】 嘌呤是构成体内核酸的重要碱基化合物,其在体内的代谢终产物为尿酸。当体内尿酸沉积时,易引发高尿酸血症和痛风。食物中的嘌呤摄入是体内嘌呤的重要来源之一,因此对食品中的嘌呤含量进行检测对人们膳食摄入有重要指导意义。嘌呤检测早在上世纪50年代就引发了关注,随着检测技术的发展,现已实现了嘌呤的微量级快速检测。本文对嘌呤检测方法进行了综述,为食品嘌呤测定提供方法参考。更多还原

【Abstract】 As a vital component of nucleic acid,the metabolic end-product of purine in human body is uric acid. Researches show that the accumulation of uric acid in blood is closely associated with the development and progression of hyperuricemia and gout. Diet is an important way to intake purine for human body; and hence,determining the content of purine in various foods is conducive to guiding people’s daily meals. In 1950 s,purine determination was firstly caught attention in academia. With the development of testing technology,micro-sensitive and fast determination of purine has been successfully achieved nowadays. This article reviews methodologies of purine determination so as to offer methods for purine determination in foods.更多还原
