Thiamine, a soluble vitamin, is an essential nutrient for humans and is important in carbohydrate metabolism, maintaining normal neural activity and preventing beriberi. Various analytical techniques have been reported for the determination of thiamine in pure form, in pharmaceutical preparations, or in biological fluids. Spectrophotometric methods suffer from poor sensitivity (mg/L detection limit). Spectrofluorometric methods usually involve the conversion of thiamine to thiochrome.2 High performance liquid chromatography requires a post-column derivatization step3 and instrumentation for electrophoresis-based methods is expensive.4... [Pg.221]

A combined microbiological assay for thiamine phosphates after separation by PPC was reported to yield a detection limit of approximately 0.02 Lig (60 pmol) of thiamine, which is still at least three orders of magnimde higher than that obtained by high-performance liquid chromatography (HPLC) with fluorescence detection. [Pg.379]

High-performance liquid chromatography (HPLC) methods have been developed in recent years to allow the rapid, sensitive, and specific analysis of thiamine and its phosphates in drugs, biological materials, and metabolites. To determine total thiamine in biological materials, samples must first be treated with Taka-diastase or acid phosphatase to hydrolyze thiamine phosphate esters to free thiamine (17,18). The complete separation of thiamine and its phosphate esters at subpico-molar level by use of HPLC was first reported by Kawasaki s group (4,17) and then continued to be developed until recent years (19,20). [Pg.380]

High-performance liquid chromatography is still a very useful technique for the quantitative determination of thiamine and its phosphate esters, not only in pharmaceutical preparations but also in biological materials, especially clinical specimens. [Pg.396]
