Abstract

The invention provides a preparation method of Astragalus polysaccharide-iron. The method comprises the following steps: 1, extracting and purifying Astragalus polysaccharides; and 2, preparing Astragalus polysaccharide-iron: dissolving the purified Astragalus polysaccharides obtained in step 1, sodium tartrate and sodium carbonate in distilled water according to a weight ratio of 15:3:5, adding an iron salt solution with the weight 0.8-0.9 times the weight of the pure Astragalus polysaccharides to obtain a solution A, allowing the solution A to go through an exchange column loaded with basic ion exchange resin at a flow velocity of 3-8BV / h, reacting for 0.5-1h, cooling the obtained reaction product, filtering resin, flushing the surface of the resin with deionized water 3-5 times, carrying out alcohol precipitation with ethanol with the concentration of 75-85%, and drying the obtained precipitate at 50-70DEG C to obtain the Astragalus polysaccharide-iron. An ion exchange resin technology is adopted to catalyze preparation of a complex from Astragalus polysaccharide and iron, the method is novel, and the prepared Astragalus polysaccharide-iron has high purity and high content, has an iron supplementing function, and also has a piglet immunity enhancing effect.

Description

【Technical field】

[0001] The invention relates to a preparation method of polysaccharide iron complex, in particular to a preparation method of astragalus polysaccharide iron. 【Background technique】

[0002] Iron deficiency anemia is one of the diseases seriously affecting human health, especially in developing countries, and its high-risk groups are pregnant or lactating women, children and infants. Iron deficiency anemia is also a common disease in mammals (especially young animals). Iron deficiency anemia in newborn piglets is a typical case. In large-scale pig farms, iron deficiency anemia in piglets is more common, and the incidence rate is as high as 80%- 90%, and the mortality rate reaches 15%-20%, causing huge economic losses. As one of the essential trace elements for the body, iron plays an important physiological role in the body. Iron is an important component of hemoglobin, myoglobin, cell chromatin and certain enzymes such as peroxidase; iron is an important ...
