Chemical Structure of Antitumor Polysaccharide, Coriolan, produced by Coriolus versicolor

Abstract

Coriolan, an extracellular polysaccharide of Coriolus versicolor is a glucan, [α]²²_D-35.0°, slightly soluble in water and has an antitumor activity. Results of periodate oxidation and methylation studies showed that the glucan has a highly branched structure possessing (1-3)-and (1-6)-linkages.
