inositol

Inositol (hexahydroxycyclohexane) is a widely distributed natural constituent of plant and animal tissues. The animal tissues richest in inositol are brain, heart, stomach, kidney, spleen, and liver, where it occurs free or as a component of phospholipids. Among plants, cereals are rich sources of inositol, particularly in the form of polyphosphoric acid esters, called phytic acids. Although there are several possible optically active and inactive isomers, considerations of inositol as a food additive refer specifically to optically inactive cis-1,2,3,5-trans-4,6-cyclohexanehexol, which is preferably designated myo-inositol. Pure inositol is a stable, white, sweet, crystalline compound. The Food Chemicals Codex specifies that it assay not less than 97.0 percent, melt between 224 and 227°, and contain not more than 3 ppm arsenic, 10 ppm lead, 20 ppm heavy metals (as Pb), 60 ppm sulfate, and 50 ppm chloride. Inositol was thought for a time to be a vitamin because experimental animals on a synthetic diet developed clinical signs that were corrected by inositol supplementation. However, no cofactor or catalytic function for inositol has been found; it can be synthesized and occurs in relatively high concentration in animal tissues. These factors argue against its classification as a vitamin. A dietary requirement in man has not been established.

CAS Ne: 87-89-8

Enhavo Analizo: precize pezas 200 mg specimeno (antaŭ-sekigitaj ĉe 105 ° C por 4h), kaj meti ĝin en 250ml Beaker. Aldoni 5ml de miksaĵo inter unu sulfata acido (TS-241) testado solvo kaj 50 anhídrido acético, kaj poste kovri la horloĝon vitro. Post varmigante sur vaporo bano por 20min, malvarmigi ĝin sur glacio bano, aldonu 100ml akvo kaj kuiru 20min. Post malvarmigo, trapasi la specimeno en 250 ml disigante funelo uzanta malgrandan kvanton de akvo. Sinsekve uzas 30, 25, 20, 15, 10 kaj 5 ml de kloroformo ĉerpi la solvon por sesfoje (unua kaŝus la Beaker). Ĉiuj kloroformo eltiraĵo estis kolektita en sekundo 250m1 disigante funelo. Lavu la miksitaj eltiraĵo kun 10ml da akvo. Metu la kloroformo solvo tra funelo kotono lano kaj kopii ŝin al 150ml antaŭ-pesis Soxhlet flakono. Uzu 10ml de kloroformo lavi la disigante funelo kaj la funelo, kaj integrigita en la eltiraĵo. Evaporar ĝin al sekeco en vaporo bano, kaj poste trapasi ĝin en forno je 105 ° C por sekigi 1h. Cool ĝin en desiccator kaj pesas ŝin. Uzu la akiris kvanton de ses inositol acetato multiplikas por 0,4167, nome la ekvivalenta kvanto de inositol (C6H12O6).

funkcio:

1. As food supplements, has a similar effect to vitamin B1. It can be used for infant foods and used in an amount of 210~250mg/kg; Used in drinking in an amount of 25~30mg/kg.
2. Inositol is an indispensible vitamin for lipid metabolism in the body. It can promote the absorption of hypolipidemic medicines and vitamins. Moreover, it can promote the cell growth and fat metabolism in liver and other tissues. It can be used for the adjuvant treatment of fatty liver, high cholesterol. It is widely used in food and feed additives, and is often added to fish, shrimp and livestock feed. The amount is 350-500mg/kg.
3. The product is one kind of the complex vitamin B, which can promote cell metabolism, improve the cell nutrient conditions, and can contribute to development, increase appetite, to recuperate. Moreover, it can prevent the accumulation of fat in the liver, and accelerate the process of removing excess fat in heart. It has a similar lipid-chemotactic action as choline, and therefore useful in the treatment of hepatic fatty excessive disease and cirrhosis of the liver disease. According to the “food fortifier use of health standards (1993)” (Issued by the Ministry of Health of China), it can be used for infant food and fortified beverages at an amount of 380-790mg/kg. It is a vitamin class medicines and lipid-lowering drug which promote the fat metabolism of liver and other tissues, and be useful for the adjuvant treatment of fatty liver and high cholesterol. It is widely used in additives of food and beverage.
4. Inositol is widely used in pharmaceutical, chemical, food, etc. It has a good effect on treating diseases such as liver cirrhosis. It can also used for advanced cosmetic raw materials, with high economic value.
5. It can be used as a biochemical reagent and also for the pharmaceutical and organic synthesis; It can lower the level cholesterol and have sedative effect.
