Spirulina Polysaccharide is a physiologically active polysaccharide extracted from Spirulina. From the exterior point of view, Spirulina Polysaccharide is a colorless or yellowish powder. Soluble in water, insoluble in fats and alcohols. Each 100 grams of Spirulina contains 6-8mg Spirulina Polysaccharide, less than 0.8/10000 content, so Spirulina Polysaccharide is also precious.
Spirulina Polysaccharide has obvious protective effect on ionizing radiation. It can improve the survival rate of NIH mice with acute radiation by 63%, and also significantly reduce the radiation induced genetic damage of bone marrow cells in mice. By inhibiting the oxidation reaction of free radicals in the body, reduce lipid peroxidation, reduce the formation of lipofuscin, can achieve slow aging effect.
There are many kinds of methods of Spirulina Polysaccharide Extraction, mostly using polysaccharide soluble in alkaline (under acidic conditions to extract polysaccharide molecules in glycosidic bond cleavage and degradation), or saline water, and the characteristics of low alcohol, insoluble in ether and ketone in organic solvent, and can use trypsin papain, enzyme treatment, enhanced the protein removal effect, improve the purity of polysaccharide of Spirulina products, can also be further purified by chromatography.
