Abstract
The present invention provides aβ-glucan extract, a preparation method and detection method therefor. The preparation method includes: S1: crushing fruiting bodies of, mixing the crushed fruiting bodies with a solvent, adding trypsin for enzymatic hydrolysis for 0.5-2 h, and separating to obtain afruiting body filter residue; S2: mixing thefruiting body filter residue with an alkali solution, carrying out ultrasonic extraction with heating, adjusting the pH value of the obtained filtrate to be neutral, and concentrating to obtain a crudepolysaccharide; S3: carrying out alcohol precipitation on the crudepolysaccharide, separating the obtained precipitate, and freeze-drying to obtain a crudeβ-glucan extract; and S4: purifying the crudeβ-glucan extract by glucose gel column chromatography to obtain aβ-glucan extract.
