Abstract

The invention relates to the technical field of traditional Chinese medicine, in particular to an extraction method and application of tremella polysaccharide. The method comprises the following steps: (1) soaking tremella with a solvent; adding water, pulping, centrifuging, and taking supernate 1; (2) adding inorganic salt into the supernate 1, stirring, centrifuging, and taking supernate 2; (3) adding the supernate 2 into an ethanol-acetone aqueous solution, standing, and sieving with a 200-300-mesh sieve to obtain a polysaccharide precipitate; and (4) redissolving the polysaccharide precipitate, heating to remove the organic solvent, and freeze-drying in vacuum to obtain the polysaccharide. The extraction method is high in tremella polysaccharide extraction rate, high in purity, short in extraction time and beneficial to industrial large-scale production.

Description

technical field [0001] The invention relates to the technical field of traditional Chinese medicine, in particular to an extraction method and application of tremella polysaccharide. Background technique [0002] Tremella, also known as white fungus, is a traditional nourishing health product in my country. Tremella has the effects of nourishing yin, moistening lungs, nourishing qi and blood. Tremella polysaccharides are derived from heteropolysaccharides isolated and purified from tremella fruit bodies and tremella cell submerged fermentation spores. A large number of studies have shown that most of the pharmacological activities of tremella are related to tremella polysaccharides. It has the functions of enhancing immunity, anti-aging, anti-tumor, reducing Blood sugar, blood fat lowering, anti-radiation and other physiological functions. At present, it is mainly used in cosmetics and food, but less in health products and medicines, and the medicinal value of white fungus ...
