AI Technical Summary

Problems solved by technology

Modern studies have shown that Achyranthes bidentata polysaccharide has the advantages of small molecular weight, strong immunoregulatory effect, no residue, and no toxic and side effects, while the esterified product of Achyranthes bidentata polysaccharide has stronger immune regulation, anti-virus, anti-tumor and other activities. Polysaccharide esterification studies are mostly synthesized in the laboratory, and there is no mature process for large-scale production

Abstract

The invention discloses a preparation method of esterified achyranthes bidentata polysaccharides, and belongs to the field of medicine. The preparation method comprises the following steps: step A, taking a raw material, achyranthes bidentata, and extracting crude polysaccharides; step B, determining the content of achyranthes bidentata polysaccharides in the crude polysaccharides with a colorimetric method; step C, esterifying the achyranthes bidentata polysaccharides with acetic acid, chlorosulfonic acid and pyridine to obtain the esterified achyranthes bidentata polysaccharides finally. Theesterified achyranthes bidentata polysaccharides obtained with the method provided by the invention has high content and better quality.

Description

technical field [0001] The invention relates to a preparation method of esterified Achyranthes bidentata polysaccharide, which belongs to the field of medicine. Background technique [0002] Achyranthes bidentata is a traditional Chinese medicinal material commonly used in my country. Its main functions are "invigorating the liver and kidney, strengthening muscles and bones, promoting blood circulation and removing blood stasis, and drawing blood downward". Modern studies have shown that Achyranthes bidentata polysaccharide has the advantages of small molecular weight, strong immunoregulatory effect, no residue, and no toxic and side effects, while the esterified product of Achyranthes bidentata polysaccharide has stronger immune regulation, anti-virus, anti-tumor and other activities. The esterification research of polysaccharides is mostly carried out in laboratory synthesis, and there is no mature process for large-scale production. Contents of the invention [0003] T...
