Abstract
A method is described for rapid determination of vitamin K3 (menadione) in vitamin premixes and mineral supplements. The menadione is extracted in the form of the bisulphite compound. After conversion into menadione the vitamin is taken up in n-hexane and is determined by HPLC without further clean-up.
摘要
描述了一种快速测定维生素预混物和矿物质补充剂中维生素K3（甲萘醌）的方法。甲萘醌以亚硫酸氢盐化合物的形式被萃取。转化为甲萘醌后，该维生素被正己烷提取，无需进一步净化即可通过高效液相色谱法进行测定。
