PROTEIN-BOUND POLYSACCHARIDES |
摘要 |
Disclosed in this invention are protein-bound polysaccharides having antitumor activities. The polysaccharides have molecular weight within a specified range and present a pattern of color reaction peculiar to the saccharides as well as a pattern of color reaction characteristic of amino acids and peptide bonds. The proton nuclear magnetic resonance spectra of the polysaccharides show peculiar absorption bands. The ratio of the polysaccharide portion to protein portion in the polysaccharides is within a specified range. The protein-bound polysaccharides can be obtained by extraction of the mycelia and/or fruit bodies of fungi belonging to Coriolus of Polyporaceae of Basidiomycetes. |
