Problems solved by technology

Traditional Chinese medicine believes that Phellinus can benefit the five internal organs, soften and harden, detoxify, stop bleeding, etc. Modern medical research has found that Phellinus has various pharmacological effects such as anti-cancer, anti-inflammation, anti-oxidation, lowering blood sugar, immune regulation, anti-angiogenesis, and liver protection. The medicinal mechanism is still unclear, which hinders the further improvement of its medicinal value

Abstract

The invention discloses phellinus baumii fruit body anticancer activity polysaccharide PBPP and a preparation method thereof.The method comprises the steps that crude polysaccharide is extracted from phellinus baumii fruit body powder through ultrasonic wave assisted hot water, precipitation is conducted with ethyl alcohol, acidic polysaccharose components are separated out through DEAE ion exchange chromatography, chromatographic purification is conducted with sephair conditioning unitryl S-100, S-200 and S-400 sequentially, eluent corresponding to eluting peaks is collected, vacuum concentration is conducted, freeze vacuum drying is conducted and a product is obtained.According to the polysaccharide PBPP and the method thereof, the purity is uniform, adverse effects on growth of normal cells do not exist, obvious inhibiting effects on growth of human cervical carcinoma cells HELA and human gastric carcinoma cells SGC-7901 are achieved, and the polysaccharide PBPP can be used for developing anticancer products.

Description

technical field [0001] The invention relates to a preparation method of polysaccharides, in particular to a polysaccharide PBPP with anticancer activity of Phellinus chinensis fruiting bodies and a preparation method thereof. Background technique [0002] Polysaccharides are polymeric carbohydrates formed by the polymerization of more than 10 monosaccharides connected by glycosidic bonds, which are widely distributed in nature as structural components, storage nutrients, and special active ingredients. Due to its unique pharmacological effects and less toxic side effects, natural active polysaccharides show broad research and application prospects. [0003] Phellinus baumii (Phellinusbaumii) is a kind of fungal fruiting body with various pharmacological effects, which is named after parasitizing on mulberry trees. Traditional Chinese medicine believes that Phellinus can benefit the five internal organs, soften and harden, detoxify, stop bleeding, etc. Modern medical researc...
