A flow injection-fluorimetric determination of thiamine is reported. The procedure is based on the oxidation of the analyte with potassium hexacyanoferrate(III) immobilized on an anionic exchange resin; the fluorescence is monitored in aqueous basic solution. Concentrations of the vitamin of 0.1-4 p
A high-pressure liquid chromatographic assay was developed for the determination of four water-soluble vitamins: niacinamide, pyridoxine, thiamine, and riboflavin. The four vitamins are assayed simultaneously in multivitamin products not containing minerals. Thiamine currently is not quantitated in
## Abstract The control of the enrichment levels in foods is difficult, due mainly to the lack of appropriate analytical methodologies. The amounts of the five Bβgroup vitamins (nicotinamide, nicotinic acid, riboflaβvin, thiamin, and pyridoxine) have been determined in enriched Brazilian foods by a
