The invention belongs to the technical field of edible and medicinal fungus polysaccharide, and particularly discloses an extraction method of phellinus igniarius polysaccharide. The invention provides an extraction method of phellinus igniarius polysaccharide, which comprises the following steps: firstly, crushing phellinus igniarius sporocarp, and degreasing to obtain phellinus igniarius powder; performing hot water extraction and alcohol precipitation on the phellinus igniarius powder to obtain phellinus igniarius crude polysaccharide; further carrying out polyamide column chromatography on the phellinus igniarius crude polysaccharide to achieve the effects of deproteinization and depigmentation to obtain primary phellinus igniarius polysaccharide; and performing DEAE-52 cellulose anion exchange column chromatography purification on the primary phellinus igniarius polysaccharide to obtain the phellinus igniarius polysaccharide. The phellinus igniarius polysaccharide extraction method provided by the invent
