Problems solved by technology

Patent ZL200610166326.7 authorizes an ultrasonic extraction method of rice bran polysaccharides. The ultrasonic power is 200-400W. The influence of extraction conditions on the purity of samples is not considered. The yield of purified polysaccharides is only 2.87%, which is difficult to apply. in actual production
[0006] Among the above technologies, the conventional polysaccharide extraction method has problems such as long time consumption, large solvent consumption, low extraction efficiency and high operating cost; however, microwave extraction will affect the molecular structure of polysaccharides, which may lead to the degradation of macromolecular chains

Abstract

The invention provides a method for extracting radiation resistant potentilla anserine polysaccharide oxide by ultrasonic waves, which comprises the following steps: extracting potentilla anserine as raw material for 30 minutes-120 minutes by ultrasonic waves and filtering under the pressure condition of 0.06 MPa-0.08 Mpa; carrying out decompressing concentration, alcohol precipitation and centrifugation on filter liquor at the pressure of 0.06 Mpa-0.08 Mpa and the temperature of 55 DEG C-65 DEG C; collecting sediments at the lower layer; freezing and drying the sediments; after dissolving by nematolyt, extracting by mixture liquid of n-butyl alcohol and chloroform, decompressing, concentrating and dialyzing, obtaining natural potentilla anserine polysaccharide. The natural potentilla anserine polysaccharide has no toxic and side effect and has better repair effect on in-vivo oxidation damage caused by free radicals generated by X-ray radiation. An antioxidant ability experiment of a small mouse radiated by a 3.5Gy X-ray indicates that the SOD activity, the T-AOC vitality and the CAT vitality are respectively improved by 66.7 percent, 54.6 percent and 105.7 percent and the MDA content is reduced by 63.2 percent of an animal with radiation damage by taking the preparation for 7 days.

Description

technical field [0001] The invention relates to a preparation method of natural polysaccharides, in particular to a method for ultrasonically extracting fern polysaccharides with anti-radiation oxidation effect. Background technique [0002] The damage of ionizing radiation to organisms has both direct effects of energy transfer and indirect effects of a large number of free radicals generated through the radiation reaction of water. The base, ribose, and phosphate bonds in DNA molecules may all be attacked by free radicals, causing various types of damage such as base and ribose oxidation, chain breaks, and protein cross-linking. Lipid peroxidation induced by free radicals can cause an imbalance in the ratio of saturated and unsaturated fatty acids in biological membranes, change the rigidity and flexibility of membrane structures, increase membrane permeability, and even disintegrate. MDA is the decomposition product of lipid peroxidation, and its content can reflect the ...
