  • Immunopotentiator and method of manufacturing the same
    Patent number: 5560914
    Abstract: In a method of producing an immunopotentiator, a plant tissue material is extracted with hot water, the insoluble material is filtered, and the filtrate thereof is treated with glucoamylase to decompose a starch, thereby obtaining a water-soluble polysaccharide. Ammonium sulfate is added in a culture filtrate obtained by culturing any one of Asp Oryzae of the Aspergillaceae and Lentinus edodes of the Basidiomycetes to obtain an enzyme complex from the precipitate. The water-soluble polysaccharide and the enzyme complex are added together to cause them to react at a pH of 4.5 for 30 to 60 minutes and then at a pH of 6.0 for 30 to 60 minutes, thereby biologically modifying the water-soluble polysaccharide.
