Abstract
PURPOSE: To prepare a protein polysaccharide having remarkable anti-tumor activity, by extracting fruit bodies of a novel fungus belonging to Agaricus genus, with an aqueous medium.
CONSTITUTION: Crushed fruit bodies of a novel fungus, Agricus heterosistes Heinem. et Goose (FERM-P No.4731) are extracted with 2W10 times volume of an aqueous medium at 50W100°C for about 1W10 hours. The extract is added with an water-soluble organic solvent such as alcohol or acetone, or with a salt such as calcium chloride. The precipitate is filtered or centrifuged, washed with ether, and dried to obtain the objective substance in powder form. The substance is pale gray powder, and 1% aqueous solution thereof exhibits pH6.0. Color reactions: positive to anthrone sulfate reaction, phenol sulfate reaction, etc.; negative to orcinol reaction.
