Embodiment Construction

[0043] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0044] Research on black fungus polysaccharides has been carried out very early. For example, Misaki et al. isolated four kinds of polysaccharides from black fungus fruiting bodies: FIA, FIB, FII and FIII, and pointed out that FIA and FII are acidic heteropolysaccharides. Both are composed of D-xylose, D-mannose, D-glucose and D-glucuronic acid. The composition molar ratio of FIA is 1.0:4.1:1.3:1.3, and that of FII is 1.0:2.1:1.0:0.6. Their structure is that the main chain is α-(1→3) mannan, and the 2 and 6 positions of mannose are substituted by D-xylose, D-mannose or D-glucuronic acid. The main...

Abstract

The invention discloses auricularia auricula polysaccharide and an application and a preparation method thereof, and the auricularia auricula polysaccharide contains D-xylose, D-mannose, D-glucose andDglucuronic acid, and has good application in reducing the levels of total cholesterol (TC) and triglyceride (TG) and increasing high-density lipoprotein cholesterol (HDLC). According to the invention, levels of total cholesterol and triglyceride can be reduced, the level of high-density lipoprotein cholesterol can be increased, the blood fat and cholesterol can be stabilized by controlling the total cholesterol and triglyceride, and the congee arteriosclerosis of blood vessels can be reduced and the metabolism of cholesterol can be promoted by increasing the high-density lipoprotein cholesterol. Therefore, the effects of reducing blood fat and cholesterol and improving human immunity are achieved.

Description

technical field [0001] The invention belongs to the technical field of food, and in particular relates to the medical application and preparation method of polysaccharides in black fungus. Background technique [0002] Black fungus (Auricularia auricular), belongs to Basidiomycetes, Auricularia, Auriculariaceae, Auricularia. Black fungus is a precious medicinal and edible colloidal fungus in my country. It is delicious, nutritious, nourishes blood and keeps the face, cures diseases and prolongs life. Black fungus polysaccharides have various functions such as regulating immune function, antithrombotic, antibacterial, hypoglycemic, antiulcer, antihepatitis and antimutagenic, hypolipidemic, and promoting serum protein biosynthesis. [0003] Black fungus polysaccharide is also accepted by everyone as a natural health product. Traditional extraction techniques include hot water extraction and dilute lye extraction. Among them, the hot water extraction method is a relatively t...
