Polysaccharide combination and preparation method and application thereof

Abstract

The invention discloses a polysaccharide combination, which is prepared by 0.01-10 percent of chitosan, 0.01-20 percent of oat beta-glucan and 70-99.98 percent of water. The polysaccharide combination is prepared through a method which comprises the following steps of: dissolving oat beta-glucan in the water to prepare oat beta-glucan dissolved water solution; and adding water into the chitosan for swelling, removing foams after one night to prepare chitosan gel, and mixing and evenly agitating the two kinds of solutions to finally obtain the polysaccharide combination which is prepared by using 0.01-10 percent of chitosan, 0.01-20 percent of oat beta-glucan and 70-99.98 percent of water. The polysaccharide combination can be used for the preparation of medical dressings, wound care agents, medicines for preventing and curing radiodermatitis, medicines for curing ulcers caused by bedsores and diabetes mellitus and dental ulcers, and medicines for promoting wound healing and reducing scars.

Description

technical field [0001] The present invention relates to a polysaccharide composition and its preparation method and use, in particular to chitosan and oat β-glucan composition and its preparation method and use, aiming to synergistically improve the radioactivity resistance of the two polysaccharides through combination Dermatitis, the ability to promote wound healing, etc., belong to the field of medical materials. Background technique [0002] Chitin is a natural polysaccharide extracted from the shells of crustaceans such as shrimps and crabs and the cell walls of fungi. It is also the second largest biological resource in nature after cellulose. Chitosan is a deacetylated derivative of chitin, which has good biocompatibility, biodegradability, natural non-toxicity and various biological activities. In recent years, chitosan, as a natural medical biological dressing, has attracted widespread attention in wound care because of its antibacterial and anti-inflammatory effec...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is aimed at the deficiencies in the prior art, provides a kind of polysaccharide composition and its preparation method and application, can solve existing chitosan material penetration Skin absorbability and oat β-glucan have no bactericidal properties. The composition prepared by this method has better anti-radiation dermatitis and wound healing effects than the respective polysaccharides used alone, and is safe and non-toxic to the human body. Toxic, non-irritating
