Beschreibung
Zusammenfassung:	The invention relates to the field of mulberry leaf polysaccharide extraction, and particularly discloses a composite extraction process of mulberry leaf polysaccharide. Mulberry leaves are used as raw materials, extraction and degreasing treatment are carried out through an organic solvent, then impurities are removed through combination of an enzymolysis method and deep eutectic solvent ultrasonic extraction, the mulberry leaf polysaccharide is obtained, and the purity of the prepared mulberry leaf polysaccharide reaches 70.8% or above. According to the method, degreasing, enzymatic extraction and deep eutectic solvent ultrasonic extraction are adopted, so that impurities contained in the mulberry leaf polysaccharide are greatly reduced, the extraction time is shortened, the extraction rate of the mulberry leaf polysaccharide is further improved, and meanwhile, the purity of the mulberry leaf polysaccharide is improved. The extraction process of the mulberry leaf polysaccharide provided by the invention has
