报道了一种灵敏、简便测定维生素Ｋ３（ＶＫ３）的荧光分析法。原理：ＶＫ３经ＳｎＣｌ２还原生成荧光性醌萘酚化合物，在波长λｅｘ＝３３４ｎｍ、λｅｍ＝４２７ｎｍ处测量，ＶＫ３在０～１８０μｇ／Ｌ范围呈线性关系。检出限为０．６２μｇ／Ｌ；测定限为２．０６μｇ...
A sensitive and simple fluorescence assay for the determination of vitamin K3 (VK3) was reported. Principle: VK3 is reduced by SnCl2 to form fluorescent quinolinolato compounds measured at λex = 334nm and λem = 427nm. VK3 shows a linear relationship in the range of 0 ~ 180μg / L. The detection limit was 0.62μg / L; the determination limit was 2.06μg ...
