Abstract
Description
technical field
[0001] The invention belongs to the field of anti-tumor macromolecule polysaccharides, and in particular relates to carboxymethylpachymaran (CMP) with a high degree of carboxymethyl substitution as a biological response regulator, a preparation method and an application thereof. Background technique
[0002] Poria cocos is the dry sclerotia of Poria cocos (Schw.) Wolf, a plant of Polyporaceae. It has been one of the "four monarchs and eight treasures" of traditional Chinese medicine since ancient times. The component pachyan has a β(1→3)-bonded glucose linear structure and a β(1→6)-bonded glucosyl branched structure. Tests have shown that Poria cocos polysaccharide without chemical modification has no anti-tumor activity, and the decoction yield of Poria cocos in boiling water does not exceed 1%. The chemically modified carboxymethylpachypolysaccharide (CMP) obviously improves the water solubility of the polysaccharide, which is beneficial to the absorption ...
