METHOD FOR PRODUCING PHOSPHORYLATED POLYSACCHARIDE

摘要

A method for producing a phosphorylated polysaccharide, characterized by mixing an aqueous solution that contains a polysaccharide (a) comprising at least one component selected from the group consisting of pullulan, glucomannan, amylose, starch, dextran and lentinan and an alkaline compound (b) with a phosphorous compound (c) comprising phosphorous oxychloride at -5 to 10°C to cause these components to react with one another. According to the production method of the invention, a phosphorylated polysaccharide can be obtained in the form of a dried solid, the dried solid can be re-dissolved and can be prepared into a powdery preparation or a tablet, and therefore the applicability of the phosphorylated polysaccharide can be widen.
