Abstract

A polysaccharide consisting glucose and aldonic acid but contains no protein and nucleic acid, whose molecular weight is 1.6X10#+[6]Da~2.6X10#+[6]Da, its terminal group carbons are of alpha-formation, the optical rotation [alpha]=+131.7 deg.-+159.4 deg., the basic matrix of the polysaccharide consists of glucose linked by 1-4 glycosidic bonds, each 17th glucose residue includes a side chain, which is a glucose molecule or an aldonic acid molecule, the proportion of glucose and aldonic acid is 2:1, they are all connected with the main chain glucose through 1-6 glycosidic bonds, the amount of glucose and aldonic acid in each mol of polysaccharide is 53:1. The polysaccharide YCP can be applied into the preparation of medicament for treating tumor. The invention also discloses the process of preparation.

Description

1. Technical field

[0001] The invention relates to a polysaccharide, in particular to a polysaccharide YCP of the marine fungus Anthropophyllum polysaccharide and its preparation method and application. 2. Background technology

[0002] Fungal polysaccharides are a type of active polysaccharides isolated from fungal fruiting bodies, mycelia, and fermentation broths, which can control cell division and differentiation, and regulate cell growth and aging. The study of fungal polysaccharides as a drug began in the 1950s and attracted people's interest as an immune booster after the 1960s. Fungal polysaccharides are currently recognized as immune enhancers with high effects. Many fungal polysaccharide preparations have been widely used clinically, and have achieved encouraging clinical effects in the treatment of autoimmune diseases, immunocompromised diseases, and tumors. However, the research on polysaccharides of terrestrial organisms (animals, plants, microorganisms, etc.) ...
