摘要
5-羟甲基糠醛(简称5-HMF)与2,4-二硝基苯肼显色,形成稳定的棕红色苯腙化合物,在可见光493nm 波长处有最大吸收;采用双波长薄层扫描法测定其含量,方法简便、快速、准确。
The stable brownish red phenylhydrazone compound formed by the combination of 5-hy- droxymethyl furfural with 2,4-dinitrophenylhydrazine showed the maximum absorption at 493nm wavelength of chromatic spectrum.So 5-hydroxymethyl furfural content can be deter- mined with dual wavelength TLC-scanning method.This method is simple,quick and accu- rate.
