IMMUNOPOTENTIATOR

摘要

An immunopotentiator comprising polysaccharides which are constituted of three saccharides, i.e., galacturonic acid, rhamnose, and glucose at a molar ratio of galacturonic acid: rhamnose: glucose of 0.6-1.0 : 0.8-1.2 : 0.8-1.2. The immunopotentiator is excellent in immunopotentiating activity and constituted of acidic heteropolysaccharides produced by microorganisms which are superior in productivity to polysaccharides originating in basidiomycetes (krestin, lentinan, etc.).
