摘要： 研究了维生素B1的氧化产物(硫色素)、维生素B2和B6混合物体系的导数-同步荧光光谱,提出了混合物体系荧光光谱被分辨开的同时测定方法。该法可不经分离直接测定复合维生素片剂中维生素B1、B2及B6,其线性范围均为0～1.0μg/mL,检出限分别为0.5、1.5及4.0ng/mL.

关键词: 维生素B1, 维生素B2, 维生素B6, 导数技术, 同步荧光光谱

Abstract: Derivative-synchronous fluorescence spectra of thiochrome(the fluorescent oxidation product of vitamin B1), vitamin B2 and vitamin B6 were studied in detail and a simultaneous determination method of these three components was presented.The detection limits of vitamins B1, B2and B6 were 0.5, 1.5 and 4.0 ng/mLrespectively, The proposed method has been used to determine vitamins B1、B2 and B6 in complex vitamin Btablets with satisfactory results.

Key words: Vitamin B1, Vitamin B2, Vitamin B6, Derivative technique, Synchronous fluorimetry
