Abstract: A purification method of fungal cell wall composition includes following steps: (1) taking a residue of a fungus fruiting body underwent extraction process for obtaining extract thereof, wherein the extract contains terpenoids, sterols, polysaccharides, or a combination thereof, and the residue contains the cell wall of the fruiting body; (2) placing the residue into an aqueous percarbonate solution to form a mixture liquid, which is reacted at a first temperature for decolorizing the residue, wherein the concentration of the aqueous percarbonate solution ranges from 5 to 20% (w/v), and the first temperature ranges from 15 to 40° C.; (3) after the decolorization process, raising the temperature of the mixture liquid to a second temperature for the mixture liquid to react, so as to digest and decompose the residue, wherein the second temperature ranges from 80 to 100° C.; and (4) filtering the treated mixture liquid to obtain a purified product.
