Process for refinement and purification of fungus polysaccharide

Abstract

This invention belonging to pre-extraction of fungus polysaccharide on pharmacy is the method to purify fungus polysaccharide with supersonic wave and hyperfiltration. The procedure is as followings: dry fungus fruiting body, leach with supersonic wave, get rid of protein, prefilter, hyperfilter to obtain different constituents and make them various products. This invention optimizes and updates fungus polysaccharide extraction method, identify kinds of fungus polysaccharides according to their effective molecular weight and molecular configuration, and achieve the goal the previous methods have never done.

Description

technical field

[0001] The invention belongs to the technical process of pre-pharmaceutical refinement of fungal polysaccharides, specifically the process of realizing the refinement and purification of fungal polysaccharides by adopting ultrasonic wave and ultrafiltration technology. Background technique

[0002] At present, the polysaccharide extraction process generally adopts water bath, enzyme extraction, chromatography, rectification, recrystallization and other processes. The disadvantages are: 1. The process is cumbersome, and the temperature and time requirements are specific. Two, there is no purification of effective components or the purification of components cannot be achieved during production. Most of the products are made of heteropolysaccharides. There are many invalid dross components in the products and the effective efficacy is low, which limits its development and use in pharmaceuticals. use. Three, the cost of the existing process is high, the effect ...
