The present disclosure provides a method for extracting aTanaka polysaccharide compound, and relates to the field of active substance extraction. This method includes: carrying out freeze-drying, pulverization, degreasing, water extraction, deproteinization, alcohol precipitation, and resin adsorption in sequence onTanaka fruiting bodies to obtain aTanaka refined polysaccharide mixture; to theTanaka refined polysaccharide mixture, adding anhydrous ethanol dropwise to perform alcohol precipitation purification, and gradually collecting precipitates, to obtainTanaka polysaccharide-10/40/60/80 active ingredients; and performing preparation via liquid chromatography on theTanaka polysaccharide-10/40/60/80 active ingredients respectively, followed by dialysis and post-treatment to obtainTanaka polysaccharide LHP-1,Tanaka polysaccharide LHP-2,Tanaka polysaccharide LHP-3,Tanaka polysaccharide LHP-4, andTanaka polysaccharide LHP-5.
