Polysaccharides are widely distributed in the natural world, perform different functions in living bodies, and are the material basis of life. In recent years, a large number of researches prove that natural polysaccharides extracted from plants, bacteria and the like have the advantages of wide sources, low toxic and side effects, high safety, wide immune enhancement function and the like, so that the polysaccharides are more and more concerned by researchers. The seaweed is used as the most abundant type of marine plant, and the polysaccharide content of the seaweed accounts for more than dry weight, so that the seaweed is the most promising type of active substance at present. Algal polysaccharides are high molecular carbohydrates formed by connecting a plurality of same or different monosaccharides through glycosidic bonds, and can be classified into red algal polysaccharides, green algal polysaccharides, brown algal polysaccharides and the like according to different sources, wherein the types and the number of the brown algal polysaccharides are the largest. The algal polysaccharide has unique structure and stable chemical property, is one kind of efficient biological adsorbent and has the functions of regulating immunity, resisting virus, resisting oxidation, resisting bacteria, diminishing inflammation, etc.
