A reversed phase HPLC method for the simultaneous determination of all monosaccharides contained in galactosaminoglycan isomers from human aorta proteoglycans.

Monosaccharides obtained by reduction and hydrolysis of galactosaminoglycan isomers, are entirely determined as their perbenzoyl derivatives by reversed phase HPLC, without removal of hexosamines prior to benzoylation. The method is suitable for the analysis of arterial proteoglycan constituent galactosaminoglycans, providing specific, precise and reproducible results. Moreover, synthesis and characterization of tri-O-benzoyl-1,6-L-anhydroidose and N-benzoyl-tetra-O-benzoyl-alpha- and -beta-D-galactosamine have been accomplished.
