A main acidic polysaccharide preparation was isolated from the leaves of Malva sylvestris L. var mauritiana Mill. It is composed of l-rhamnose, d-galactose, d-galacturonic acid, and d-glucuronic acid in the molar ratio of 22:6:22:11, and it contains 7.7% peptide. It was homogeneous by electrophoresis and gel chromatography, which gave a value of 11 000 as molecular weight. The structure of the polysaccharide component was elucidated by methylation analysis and partial hydrolysis. The substance showed considerable anticomplementary activity.
