Abstract: Provided is a method for quantitating a saccharide in a liquid sample. The method comprises incubating the liquid sample with 2,3-naphthalenediamine in the presence of iodine to allow a naphthimidazole group to be linked to the saccharide to obtain a first mixture; obtaining an 1H-NMR spectrum of the first mixture; and comparing, in said 1H-NMR spectrum, the intensity or integral of a proton signal corresponding to the saccharide to the intensity or integral of a proton signal corresponding to an internal standard present in the first mixture.
