| Abstract: | It has been established that a polysaccharide from the pith of the stems ofAlthea flavovirens Boiss et Buhse growing in Azerbaidzhan (environs of the village of Dzhul'fy) has a branched molecule consisting of residues of ribose, rhamnose, glucose, and glucuronic and galacturonic acids (3:6:3:7:2). Among the products of the methylation of the polysaccharide reduced at the carboxy groups the following sugar derivatives have been identified: 2,3,4-tri-O-methyl-L-rhamnose, 3,4-di-O-methyl-L-rhamnose, 2,3,4,6-tetra-O-methyl-D-glucose, and 2,3,6-tri-O-methyl-D-glucose and 2,3,6-tri-O-methyl-D-galactose (unresolved mixture), and also 2,6-di-O-methyl-D-glucose (2:10:24:7:2).V.
