Lentinan is extracted from shiitake mushrooms β- Glucan. Lentinan has been approved as a biological response regulator for gastric cancer in Japan.

Any sugar that can be hydrolyzed into multiple monosaccharide molecules or their derivatives is called a polysaccharide.

It is a macromolecular compound formed by condensation and dehydration of twenty to tens of thousands of monosaccharide molecules. Polysaccharides can be condensed from a monosaccharide, such as starch, cellulose, etc., to form homopolysaccharides; It can also be condensed from different monosaccharides or their derivatives, such as hemicellulose, which is called heteropolysaccharides. Plants, animals, and microorganisms in nature all contain polysaccharides. Polysaccharides can exist in both free and bound forms with proteins. The commonality of plant polysaccharides is their naturalness, health value, and unique water-soluble colloidal properties, which can endow food with high nutritional value, stable and palatable tissue structure, exquisite appearance, and unique taste, and extend shelf life.

Effect:

1. Anti tumor. Mushroom polysaccharides obtained from shiitake mushrooms have strong anti-tumor activity.

2. Enhance immune function. Different polysaccharides have different immune promoting effects. Mushroom polysaccharides are ideal immune promoters. Tremella polysaccharides can promote the transformation of lymphocytes, enhance the phagocytic function of mouse peritoneal macrophages, significantly promote the synthesis of liver protein nucleic acid, promote bone marrow hematopoietic function, and improve humoral immunity.

Black fungus polysaccharides can effectively increase the phagocytic index and percentage of mouse macrophages. Polysaccharides extracted from garlic, radish, etc. have different enhancing effects on T lymphocytes, B lymphocytes, and macrophages, which can enhance the body's cellular immune function.

3. Lower blood sugar and blood lipids. The polysaccharide with hypoglycemic effects is bovine milk glucan. Mushroom polysaccharides have a cholesterol solubilizing effect. Auricularia polysaccharide has the effect of alleviating atherosclerosis.
