Description
Technical field
The invention belongs to the polysaccharide compound technical field, particularly a kind of Chinese yam polysaccharide-iron complexes and preparation technology thereof.
Background technology
Polysaccharide is from the natural macromolecular material in higher plant, animal, the microorganism cells, it is the high molecular polymer that forms in the biological vital movement, be the important component part of Living organism, with protein, nucleic acid and become most important three kinds of biomacromolecules.Polysaccharide molecular weight is big, polarity is big, complex structure, be difficult for to form crystallization, has very big difficulty aspect separation and purification and structure evaluation.Chinese scholars studies show that polysaccharide not only can be treated the cancer that body immune system is subjected to major injury, can treat the damaged disease of panimmunity again.As medicine, the more important thing is that its cytotoxicity is minimum.During tumour, it directly kills the tumour cell of growing unlike general chemotherapeutics in treatment, thereby but promote cell and humoral immune reaction to reach to suppress and the effect of elimination tumour cell, very little to normal impact cell.
China's Chinese yam aboundresources, only the Wuzhi of Henan Province's JIAOZUO AREA, Wen County, Qinyang (celebrating mansion, old genus bosom, the rapid-result RHIIZOMA DIOSCOREAE frOm Henan of China Dioscorea of the institute Chinese yam that produces opposita Thunb) annual output Chinese yam is healed 1,000,000 tons.Place of production Chinese yam still adopts traditional method to concoct process complexity, labor intensive at present.And concocting process will be bleached with sterilization with sulfur fumigation, may cause sulphur residual too high or produce harmful sulfide.
Summary of the invention
The object of the invention is to provide a kind of Chinese yam polysaccharide-iron complexes and preparation technology thereof.
For reaching above-mentioned purpose, the present invention adopts following technical scheme: Chinese yam polysaccharide-iron complexes, and wherein the mass content of iron is 20-40%, Chinese yam polysaccharide content is between 10-50%.
It is Chinese yam polysaccharide-ferrous iron mixture, 25 ℃ in 100 ml waters solubleness be 6-7 gram.
It is Chinese yam polysaccharide-ferric iron mixture, 25 ℃ in 100 ml waters solubleness be 10-12 gram.
Chinese yam polysaccharide-iron complexes preparation technology is got Chinese yam polysaccharide and water-soluble citrate or tartrate and is dissolved in the distilled water, and heating in water bath, stirring drip the aqueous solution of ferrous iron or ferric compound down, dropwise and react 0.5-2 hour again; Cooling adds ethanol alcohol precipitation, washing in the reaction solution, get Chinese yam polysaccharide-iron complexes; The mass ratio of Chinese yam polysaccharide and water-soluble citrate or tartrate, ferrous iron or ferric compound is 1.5-8.5: 3-6: 3-10.5.
Citrate trianion is trisodium citrate or citric acid tri potassium, and tartrate is sodium tartrate or soluble tartrate, and the compound of iron is iron(ic) chloride or ferrous ammonium sulphate.
Citrate trianion is a trisodium citrate, and tartrate is a sodium tartrate.
Polysaccharide concentration is 1-5g/250ml, and trisodium citrate concentration is 0.1-0.3mol/l, and the concentration of iron(ic) chloride is 0.2-0.6mol/l, reaction solution PH=7-8.
Polysaccharide concentration is 1-5g/250ml, and sodium tartrate concentration is 0.1-0.3mol/l, and the concentration of ferrous ammonium sulphate is 0.2-0.6mol/l, reaction solution PH=7-8.
Alcohol precipitation gained filter residue with 95% ethanol, dehydrated alcohol, acetone, ether washing, gets powdery Chinese yam polysaccharide-iron complexes through vacuum-drying or lyophilize successively.
The present invention utilizes resourceful Chinese yam first, from the Chinese yam polysaccharide in the Chinese yam and ferrous iron or the reaction of ferric water-soluble salt, makes Chinese yam polysaccharide-iron complexes (complex compound).Utilize mass content that atomic absorption, phenanthroline spectrophotometry and sulfuric acid phenol colour developing spectrophotometry goes out iron wherein between 20-40%, the mass content of polysaccharide is between 10-50%.Under 25 ℃ of temperature, the Chinese yam polysaccharide-solubleness of ferrous iron mixture in 100 ml waters is the 6-7 gram, and the Chinese yam polysaccharide-solubleness of ferric iron mixture in 100 ml waters is the 10-12 gram.Chinese yam polysaccharide-iron complexes dissolving out capability and stability better, and its aqueous solution is neutral, near the human body fluid pH value.Alternative existing benefit chalybeate (ferrous sulfate, the acid of coral amber are ferrous, Ferrous Gluconate etc.) to compensating iron for human, can avoid using existing stimulation side effect of mending chalybeate to the human intestines and stomach.In the reaction process, iron ion and citrate ion form the complex compound ironic citrate, ironic citrate is converted into citric acid polymerization iron under alkaline condition, Chinese yam polysaccharide is with the surperficial and polymerization iron phase mutual effect at polymerization iron nuclear of its sugar chain, generate stable Chinese yam polysaccharide-citric acid-polymerization iron complexes, i.e. Chinese yam polysaccharide-iron complexes.Preparation technology among the present invention, raw material is easy to get, and processing step is few, and the no three wastes produce.
