Abstract: Objective To establish new national reference standards for fructosazine and deoxyfructosazine used for impurity determination of raw materials or preparations of glucosamine in order to ensure the quality of products of glucosamine. Methods UV, HRMS, 1HNMR, 13CNMR, 2D NMR and CD were used to confirm the structure while the content of the product was calculated using the mass balance method before being verified by the QNMR method. Results The structure of this product was identified and the contents of fructosazine and deoxyfructosazine were assigned as 98.0% and 95.1% respectively. Conclusion Fructosazine and deoxyfructosazine have been established as national reference standards for the first time, which can be applied to quality control of glucosamine and related products.

Key words: fructosazine, deoxyfructosazine, glucosamine, establishing national reference standards
