Zusammenfassung:	The invention discloses a preparation method of a natural antioxidant tricholoma lobayense heim polysaccharide, comprising the following steps of: drying tricholoma lobayense heim until the tricholoma lobayense heim has a constant weight and then smashing and sieving; then digesting obtained powder with hot water, rotatably evaporating and concentrating an extracting solution, and taking liquid supernatant after centrifuging; and finally, concentrating the liquid supernatant, taking sediments after ethanol precipitation and centrifuging, and freezing and drying, so as to obtain the tricholoma lobayense heim polysaccharide. The tricholoma lobayense heim polysaccharide is obtained by extracting is a natural product with high antioxidant activity and can be used for obviously cleaning.O2 generated by a pyrogallic acid self-oxidation system, particularly a component of TL-3. When the concentration is 500 microgram/mL, the clearance rate can reach 75.6%, which is only 15.4% lower than Vc. Therefore, the trichol
