| 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. |
