Beschreibung
Zusammenfassung:	The invention provides lycium barbarum polysaccharide, and the extraction method of the lycium barbarum polysaccharide comprises the following steps: extracting lycium barbarum polysaccharide in lycium barbarum by using a hydrophilic ionic liquid aqueous solution through high-speed shearing, dispersing and emulsifying assistance, then converting the hydrophilic ionic liquid into hydrophobic ionic liquid through double decomposition reaction with NH4PF6, transferring the lycium barbarum polysaccharide into a water phase, and separating the lycium barbarum polysaccharide from the lycium barbarum polysaccharide to obtain the lycium barbarum polysaccharide. The method comprises the following steps: extracting most protein and pigment small molecules into a hydrophobic ionic liquid phase, collecting a water phase for deproteinization, decoloring, dialyzing by using a 3500Da dialysis bag, and then collecting, freezing and drying to obtain dry polysaccharide powder. And recycling the ionic liquid reagent in the hydr
