| Abstract: | It has been shown that the carbohydrates ofSymphytum asperum L. — a promising fodder plant — include water-soluble polysaccharides, pectin substances, protopectin, hemicelluloses, a glucomannan, and cellulose. The quantitative amounts of the polysaccharide fractions in the raw material have been established and their characteristics are given. The protopectins of the leaves and stems ofSymphytum asperum L. have been characterized. Their macromolecules are based on a fragment constructed of D-galacturonic acid residues linked by  -glycosidic bonds.M. V. Lomonosov Odessa Technological Institute of the Food Industry.
