A representative mucilage, named Althaea-mucilage R, was isolated from the roots of Althaea rosea CAVAILLES (hollyhock). The final preparation was homogeneous as determined by ultracentrifugal analysis, cellulose acetate and glass-fiber electrophoresis, and gel chromatography. Its water solution gave an intrinsic viscosity value of 33.4. It was composed of partially acetylated acidic polysaccharide and protein in a ratio of approximately 10.3 : 1.0, and its molecular weight was estimated to be 41700. The polysaccharide moiety was composed of D-galactose, D-glucose, L-rhamnose, D-galacturonic acid, and D-glucuronic acid in the molar ratio of 2 : 1 : 6 : 4 : 6. Reduction of carboxyl groups followed by methylation analysis, and partial acid hydrolysis studies made it possible to deduce the structural features of the polysaccharide moiety in the mucilage (Chart 4).
