Pumpkin polysaccharide is a water-soluble heteropolysaccharide extracted from pumpkin and has many biological activities and functions. The extraction and purification of pumpkin polysaccharide has attracted more and more attention.

The polysaccharide extract obtained by the general separation method contains many impurities, so the crude extract must be further purified. The macroporous adsorption resin extracts and purifies pumpkin polysaccharide base with strong adsorption capacity, easy desorption, high yield and low cost. This method has become a common method in the world.
