Preparation method and application of multiflower knotweed vine polysaccharide chelate zinc

Abstract

The invention relates to a preparation method and application of multiflower knotweed vine polysaccharide chelate zinc. The problems of preparation of the multiflower knotweed vine polysaccharide chelate zinc and application thereof in preparation of health-care products and medicaments can be effectively solved. The method comprises the following steps of: extracting multiflower knotweed vine powder in water in a weight ratio of 1: (8-10) at the temperature of 80 and 100 DEG C for 2 to 4 times and for 1.5 to 3 hours every time, filtering, combining the filtrate, performing concentration tillthe relative density is 1.1 to 1.3, and obtaining multiflower knotweed vine polysaccharide concentrate; mixing the multiflower knotweed vine polysaccharide concentrate and zinc sulfate solution in equal volume, stirring the solution uniformly, regulating the pH value to be between 6.0 and 8.5 by using sodium hydroxide solution, reacting for 2 to 3 hours at the temperature of between 70 and 90 DEGC, and obtaining multiflower knotweed vine polysaccharide chelate zinc solution; and dialyzing the multiflower knotweed vine polysaccharide chelate zinc solution, adding 95 percent ethanol into the dialyzed solution till the ethanol content reaches 80 to 90 percent, performing standing and alcohol precipitation for 10 to 24 hours, filtering, obtaining sediment, drying and crushing, and thus obtaining the multiflower knotweed vine polysaccharide chelate zinc. The method is simple, the raw materials are rich, the product has wide application, the problem of low absorption of the conventional zinc supplementing product is solved, and the product has the effect of improving the immunity of the body and is an innovation of Chinese medicaments.

Description

technical field [0001] The invention relates to the field of medicine, in particular to a preparation method and application of Polygonum multiflorum polysaccharide chelated zinc. Background technique [0002] Zinc is a component or coenzyme of six major enzymes and 200 metalloenzymes in the human body. It plays a wide range of roles in systemic metabolism, such as participating in the synthesis of nucleic acids and proteins, cellular and humoral immune processes, and energy metabolism. It is an essential trace element for the human body. In the past and now, zinc supplements such as zinc sulfate and simple zinc gluconate are mostly used in clinical zinc supplementation. Most of them are absorbed in the form of ions in the body. The formation of insoluble matter leads to a large amount of loss; on the one hand, it is affected by factors such as insufficient binding protein, and the absorption rate is low.

Problems solved by technology

In the past and now, zinc supplements such as zinc sulfate and simple zinc gluconate are mostly used in clinical zinc supplementation. Most of them are absorbed in the form of ions in the body. A large amount of loss is caused by the formation of insoluble matter; on the one hand, due to factors such as insufficient binding protein, the absorption rate is low

[0003] Polysaccharides are a class of carbohydrates with large molecular weight and complex structure. Studies have shown that polysaccharides have immune regulation, anti-virus and anti-cancer effects. Due to the high content of polysaccharides, the preparation process is relatively simple, and it is easy to be absorbed by the body, so its It is of great application value in the industries of medicine, health and food, but there is no report on the preparation and application of polysaccharide chelated zinc from Polygonum multiflorum
