Embodiment 1

[0037] Embodiment 1: Preparation of selenized maca polysaccharide

[0038] (1) Add 0.5 g of maca polysaccharide to 0.5% nitric acid solution for dissolving, add 0.1 g of sodium selenite, and heat at 30°C for 9 hours to obtain a selenization reaction solution;

[0039] (2) Cool the selenization reaction solution to 20° C., centrifuge, collect the supernatant, and perform dialysis;

[0040] (3) Concentrate the solution in the dialysis bag and dry it in vacuum to obtain 0.1 g of selenized maca polysaccharide with a selenium content of 10 μg / mg.

Embodiment 2

[0041] Embodiment 2: the preparation of selenized maca polysaccharide

[0042] (1) Add 10 g of maca polysaccharide to 2% sulfuric acid solution to dissolve, add 1 g of selenous acid, and heat at 90° C. for 1 hour to obtain a selenization reaction solution;

[0043] (2) Cool the selenization reaction solution to 10°C, centrifuge, collect the supernatant, add it to the ultrafiltration membrane, and perform membrane filtration;

[0044] (3) Concentrate the solution in the ultrafiltration membrane, and freeze-dry to obtain 2.8 g of selenized maca polysaccharide, with a selenium content of 1 μg / mg.

Embodiment 3

[0045] Embodiment 3: the preparation of selenized maca polysaccharide

[0046] (1) 5 g of maca polysaccharide was added into 5% phosphoric acid solution to dissolve, 0.33 g of sodium selenite was added, and heated at 60° C. for 5 h to obtain a selenization reaction solution;

[0047] (2) Cool the selenization reaction solution to 35° C., centrifuge, collect the supernatant, and perform dialysis;

[0048] (3) The solution in the dialysis bag was concentrated and freeze-dried to obtain 1.5 g of selenized maca polysaccharide with a selenium content of 5 μg / mg.

Abstract

The producing method and usages of the selenium maca polysaccharide are shown below. The above mentioned producing method includes three steps. The first step is to put the maca polysaccharide into the acid water solution and dissolve. Then put in the selenide agent and heat for reaction. And then the selenide reaction solution is achieved. The second step is to cool down the selenide reaction solution achieved in the first step. Then separate the solid and liquid. Collect the upper clean liquid and conduct the purification. The third step is to concentrate the upper liquid achieved in the first step. Dry it and then the selenium maca polysaccharide is achieved. The selenium maca polysaccharide produced by this way has both functions of the maca polysaccharide and the organic selenium. it has improved the additional value of the maca polysaccharide so that it can be well absorbed and used by the bodies. The product shows higher biological activity and the application future is quite wide.

Description

technical field [0001] The invention relates to a chemical synthesis method, in particular to a selenized modified maca polysaccharide and its preparation method and application, belonging to the field of deep processing of maca polysaccharide. Background technique [0002] Selenium is an essential trace element for the human body and the main active ingredient of glutathione peroxidase, which can directly or indirectly remove oxygen free radicals in the body, inhibit lipid oxidation or peroxidation, and block the pathogenicity of active oxygen and free radicals It protects cells from peroxide damage, maintains the stability of cell membranes, and plays an important role in animal growth, reproduction, immunity, anti-infection, and anti-stress. Surveys show that more than two-thirds of the population in China is in a selenium-deficient or low-selenium belt, and the amount of selenium ingested by daily diet cannot meet the minimum requirement, which greatly increases the inci...
