Abstract

The invention relates to a preparation method and application of fritillaria pallidiflora total polysaccharide. The preparation method comprises the steps that bulbs of fritillaria pallidiflora are naturally dried, mechanically smashed, and sieved so as to separate impurities, degreasing is conducted by using petroleum ether, after nature air drying is conducted on the product, a solvent is utilized to conduct continuous extraction, then centrifugation and concentration are conducted, precipitation is conducted by using absolute ethyl alcohol, the centrifugation is conducted again, vacuum freezing drying is conducted on polysaccharide precipitation, and crude polysaccharide with water solubility, hot water solubility and acid solubility is prepared. The crude polysaccharide is purified, and subjected to deproteinization and dialysis, and three neutral sugars are obtained after separation and purification of ion exchange resin and polydextran gel. The total extraction rate of the crudepolysaccharide obtained by adopting the method can reach 30%, the polysaccharide part is verified to have antioxidant activity, and have a cleaning ability to a free radical. Finding a new antioxidantfrom natural plants is a new direction of the development of modern medicine and food industries. There is important practical meaning to research antioxidation of polysaccharide and derivatives thereof and develop new natural antioxidants. Research on the preparation method and the application of the fritillaria pallidiflora total polysaccharide provides references for the application and development of fritillaria pallidiflora polysaccharide in antioxidant and anti-aging functional food products.

Description

technical field [0001] The invention relates to a preparation method and application of total polysaccharides of iberia japonicus. Background technique [0002] Ili Fritillaria is the dry bulb of Fritillaria pallidiflora Schrenk or Fritillaniawalujewii Regel, a plant of the Liliaceae family. The main place of production of the plant is Xinjiang. The former is distributed in Yining, Suiding and Huocheng in the northwest of Xinjiang. The latter is distributed in the Tianshan region of Xinjiang. Yili fritillary is mostly born in forests, grasslands and sandy hillsides at an altitude of 1200-2500 meters, and is especially suitable for planting in arid areas in Xinjiang. Ancient Uyghur medicine used local Fritillaria to treat diseases. In the late 18th century, it had a history of clinical use in Uyghur medicine. Ili Fritillaria has been recorded in the "Chinese Pharmacopoeia" (2000 edition) and the first volume of "Uyghur Medicine Chronicles". Due to the high yield of Ili Fri...
