Abstract

The invention discloses a Boletus calopus polysaccharide, and a preparation method and an application thereof. The polysaccharide is obtained through water extraction, alcohol precipitation, protein removal, ion exchange column chromatography and dialysis concentration of Boletus calopus sporophores, and is heteropolysaccharide composed of alpha-D-galactose and beta-D-glucose, wherein a molar ratio of the alpha-D-galactose residue to the beta-D-glucose residue is 5:1. The polysaccharide has a significant activity, and has a significant inhibition activity to multiple tumor cells.

Description

technical field [0001] The invention belongs to the technical field of fungal polysaccharide applications, and in particular relates to a polysaccharide from Boletus americana and its preparation method and application. Background technique [0002] Polysaccharides are natural biological macromolecules that are linked by more than 10 monosaccharides through glycosidic bonds. At present, studies have found that polysaccharides have a variety of physiological effects, such as immune regulation, anti-tumor, anti-virus, anti-oxidation, hypoglycemic and so on. Moreover, the two-dimensional NMR spectrum ( 1 H- 1 The rapid development of technologies such as H NMR, HSQC, HMBC, etc.), gas chromatography-mass spectrometry (GC-MS), high-performance liquid chromatography (HLPC), X-ray diffraction, and scanning electron microscopy have largely promoted the Structural studies. [0003] Boletus reticulates Schaeff. belongs to Agaricaceae, Boletaceae, and Boletus genus, and is edible a...
