Abstract:
1. A method for preparing a bioactive glycoprotein fraction comprising in order the steps of: extracting the fruiting body of extracting the resulting residue with hot water at 100–120° C., and adding ethanol to the hot water extract to a final ethanol concentration of 50–75% by volume; removing the resulting precipitate and floating matter after standing at 40°–10° C. for 8–12 hours, wherein said floating matter is on the liquid or in the liquid or adhering matter to vessel wall; collecting a fraction molecular weight equal to or greater than 14,000 daltons from the supernatant; and wherein the bioactive glycoprotein fraction comprises a bioactive glycoprotein having a protein to saccharide ratio ranging from about 75:25 to about 90:10.
