Abstract: A method for the determination of monosaccharides in a sugar composition by simultaneous quantitative analysis of monosaccharides constituting the sugar composition, comprising the steps of: (1) liberating sialic acid from the sugar composition with sialidase or an acid, (2) converting the released sialic acid into N-acylmannosamine with sialic acid aldolase, and (3) acid hydrolyzing the N-acylmannosamine and a sugar residue. The method allows pretreatment in a single reactor and the sugar composition including sialic acid can be obtained by a single analysis by HPLC, etc.
