More Information
Summary:The invention relates to a method for separating and purifying a chitosan oligosaccharide monomer, which is performed according to the following steps: 1) preparing solution of chitosan chitooligosaccharide: dissolving chitosan oligosaccharide into water or hydrochloric acid solution of which the concentration is between 0.1 and 1.0 mol per liter according to a concentration of between 20 and 70 percent, and when the chitosan oligosaccharide is completely dissolved, performing suction filtration to obtain filtrate which is the chitosan chitooligosaccharide solution; 2) sampling the chitosan chitooligosaccharide solution in a cation exchange resin column, performing elution by using hydrochloric acid of which the concentration is between 2.0 and 3.0 mol per liter at a flow rate of between 100 and 600 milliliters per hour, using an automatic fraction collector to perform collection, and using a acid-base titration method and an HPLC method to detect the hydrochloric acid content and thesugar content in the coll
