  • Title: Detection of reaction products of thiamin degradation by catechol derivatives.
    Author: Hayakawa F, Ueda K, Murata K.
    Journal: J Nutr Sci Vitaminol (Tokyo); 1984 Aug; 30(4):319-26. PubMed ID: 6512604.
    Abstract:
    To clarify the mechanism of thiamin degradation by catechol derivatives, thiamin and its analogues were incubated with caffeic acid or catechol in 1/15 M phosphate buffer pH 7.4 at 48 degrees C or 50 degrees C. Using thin-layer chromatography and high-performance liquid chromatography, several unknown intermediates of the reaction product, which may have both pyrimidine and catechol moieties, were detected.
