The invention relates to a water-soluble barm Beta-dextran and a preparation method thereof. In the water-soluble barm Beta-dextran chain, Beta-1, 3-dextran is taken as a main chain, Beta-1, 6-dextran is taken as a branched chain, the molecular weight is 0.08 to 0.2 million Daltun. The preparation method of the water-soluble barm Beta-dextran includes the following steps of: water extraction, alkali extraction and impurity processing. The preparation technique of the invention is simple; the technique parameters are easy to be operated and controlled; both the yield and the purity of the product water-soluble barm Beta-dextran are higher. The obtained water-soluble barm Beta-dextran has remarkable immune activation effect and especially can improve the phagocytic function and the antibodyformation capacity of a macrophage to a large extent, thereby improving the body immunity and resistance. The water-soluble barm Beta-dextran can be widely applied in the fields such as food, dairy food ...

The invention belongs to the field of medicaments, and provides a method for preparing Griflola frondosa proteoglycan. The Griflola frondosa proteoglycan prepared by the method has the sugar content of 50 to 90 percent and the protein content of 10 to 50 percent. The preparation method comprises the following steps of: autolyzing and enzymolyzing strains; and performing microfiltration on the enzymolysis extract, and then performing ultrafiltration, chromatography and drying to obtain the Griflola frondosa proteoglycan. The method has the advantages of simple process, easy control on process parameters, high yield and purity of the product Griflola frondosa proteoglycan, and suitability for industrial production. The prepared Griflola frondosa proteoglycan can be widely applied to medicaments, foods, food additives and other light industries.
