Astragalus Polysacharin Powder Usage and Synthesis.

Astragalus polysaccharide is a water-soluble heteropolysaccharide extracted, concentrated and purified from the dried roots of Astragalus membranaceus or Astragalus membranaceus, family leguminosae. It is light yellow, fine powder, uniform and without impurities, with moisture-attracting property.

Astragalus polysaccharide consists of hexanedioic acid, glucose, fructose, rhamnose, arabinose, galacturonic acid and glucuronic acid, etc. It can be used as immune promoter or regulator, and it also has the functions of anti-virus,anti-tumour, anti-aging, anti-radiation, anti-stress, anti-oxidation and so on.

Uses of Astragalus Polysacharin.

Astragalus polysaccharide injection can be used for the treatment of livestock and poultry variant viral colds, acute and chronic respiratory diseases and viral diseases caused by bacterial and mycoplasma infections; circovirus, blue ear disease, pericarditis, encephalitis, infectious gastroenteritis, epidemic diarrhoea, mumps also has an adjunctive therapeutic effect; in addition to the mouth, nose and feet of the pustules and virulent infectious diseases immunisation failure to prevent proliferation and remedial effect.

1、Improve the immunity of the body, prevent and control the immune system syndrome of livestock and poultry,with the function of promoting the growth of animals, improve the appetite of chickens, digestion, disease resistance, survival rate, feed conversion rate increased by 9.0% and 10.1%, can significantly increase the laying rate of laying hens, reduce the ratio of feed to egg and mortality rate, and can improve the performance of the peak of the laying of eggs in laying hens.

2, Astragalus polysaccharide can block the adhesion of Pseudomonas aeruginosa in the respiratory epithelium, and has a restorative effect on the tracheal mucosal epithelium of mice with chronic bronchial lesions, which can play a role in anti-Pseudomonas aeruginosa infection.

3、Certain polysaccharides contained in traditional Chinese medicine are important immune agents, such as ginseng polysaccharides, mushroom polysaccharides, astragalus polysaccharides, antler velvet polysaccharides and so on.

Astragali polysaccharide on cellular immunity, humoral immunity, molecular immunity, complement immunity, etc.has a comprehensive enhancement of the role of patients with frequent colds and flu has a preventive effect, for patients with chronic infections with the efficacy of supporting the positive toxin, but can activate the antibody,which will make rheumatoid arthritis, leucosis oral ulcers, uveitis aggravation, polymyositis and immune liver disease, ALT, AST, CK, and other liver enzymes, such as myocardial enzyme titers, significantly higher. Adult Steele's disease fever is difficult to decline.

4, by astragalus polysaccharide in the separation of two polysaccharides, astragalus polysaccharide - Ⅰ and astragalus polysaccharide - Ⅱ, both make the liver, spleen cells in the alkaline ribonuclease (RNase) activity decreased significantly, resulting in the accumulation of RNA content of tissues, so that RNA anabolism is reduced.

Toxicological of Astragalus Polysacharin.

Astragalus polysaccharide iv, the LD50 of mice is 6.34±0.39g/kg. Normal people who take astragalus can experience side effects such as conscious fire, dry mouth, dry lips, sore tongue, dry stools, chest distension, short sleep, and easy to get excited.

Measurement methods of Bulk Astragalus Polysacharin Powder.

Precision measurement of the control solution and test solution 10ml, respectively, placed in a 50ml measuring flask, add 2% phenol solution 2.5ml, 25ml of sulfuric acid, shaking, placed in a water bath heated for 15 minutes,cooling, diluted with water to the scale, shaking, according to the spectrophotometric method (Appendix), the absorbance at 490nm wavelength were measured, calculated, that is, obtained. The solution prepared by adding 10ml of distilled water was used as blank solution.
