A present invention relates to a method for quantitatively determining sugar-alcohols characterized by passing test samples containing sugar-alcohols, proteins, and saccharides through a column filled with basic anion-exchange resins which have a protein-removing ability and a saccharide-removing ability, and then quantitaing the sugar-alcohols in the effluent out of the column, a column filled with said resins and an aqueous solution of boric acid, and a kit. Sugar-alcohols such as 1,5-anhydroglucitol and the like have been calling attention as markers for diabetes mellitus recently.

Method for quantitatively measuring sugar-alcohol, column and kit

The present invention relates to a method of quantitative assay for 1,5-anhydroglucitol which comprises oxidizing 1,5-anhydroglucitol in an aqueous solution of a specimen in the presence of an electron acceptor to produce a compound represented by formula (1) below or a hydrate thereof represented by formula (2) below and quantitatively determining 1,5-anhydroglucitol from a consumption amount of said electron acceptor in said aqueous solution of a specimen or from a production amount of the reduction product of said electron acceptor produced or from an amount of oxidized product of 1,5-AG represented by formula (1) or formula (2). ##STR1##
