A preparation method of apolysaccharide rich in β-glucan includes: (1) extracting thepolysaccharide to obtain a filtrate; (2) concentrating the filtrate to obtain a supernatant; (3) precipitating a crudepolysaccharide from the supernatant using anhydrous ethanol to obtain a first precipitate; and (4) purifying the first precipitate to obtain thepolysaccharide. Thepolysaccharide rich in the β-glucan has stable quality, and its yield, polysaccharide content and β-glucan content are significantly improved compared with water extraction and alcohol precipitation methods in the related art. In vitro pharmacological experiments prove that thepolysaccharide rich in the β-glucan has good anti-inflammatory activity and can be applied to preparation of drugs or health foods.
