Abstract: In order to obtain 4-O-methyl-D-glucurono-D-xylan fractions in the range of relative molecular masses 7000-8500, optimal conditions of oxidative-acidic depolymerization in the medium of sulfuric acid and hydrogen peroxide were elaborated. The used methods for isolation of degradation products, i.e. gel filtration, dialysis, and ultrafiltration were evaluated from the point of view of yield, properties of product, and primary structure of polysaccharide fractions.
