Recent Advances in Bee-Pollen Polysaccharides

Bee pollen is a natural nutrient rich in protein, polyphenols, flavones and other bioactive ingredients. At home and abroad, bee pollen has a long history of medicine and dietary use. As the main non-toxic active component of bee pollen, its polysaccharide has good anti-tumor, immune enhancement and anti-oxidation effects. However, due to the limitations of the technology and the complexity of polysaccharide, it has received relatively less attention than other nutrients in bee pollen. This paper systematically compares and summarizes the extraction, separation, and purification techniques, composition and biological activities of bee pollen polysaccharides in recent ten years, in order to provide references for the further development of bee pollen polysaccharides.
