Abstract: The invention provides prepared polygonum multiflorum polysaccharide and an application thereof in preparing an anti-aging medicament. A preparation method of the processed polygonum multiflorum polysaccharide comprises the following steps of: crushing polygonum multiflorum, and refluxing and degreasing by use of 95% ethanol; filtering out a solvent, drying filter residues, and then refluxing and extracting by virtue of 80% ethanol; filtering out the solvent, and drying filter residues to obtain degreased processed polygonum multiflorum powder; adding water into the degreased polygonum multiflorum powder, extracting in a water bath at a constant temperature of between 60 and 90 DEG C under a condition that the pH value is 7.0; filtering, mixing filtrates, and concentrating until the relative density is 1.05; adding amylase, and standing overnight at 37 DEG C; filtering, adding ethanol into filtrate to regulate the alcohol density to be between 50 percent and 80 percent, and standing overnight; and filtering, and removing protein and pigment from precipitate to obtain the processed polygonum multiflorum polysaccharide. The processed polygonum multiflorum polysaccharide can be applied in preparing the anti-aging medicament, has an excellent treatment effect, is a Chinese medicinal preparation, has the advantages of small toxic and side effects, safety, reliability and wide application field, and can be used for development of capsules, granules, tablets and the like.
