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-Nr: 87-89-8

Inhaltsanalyse: Genau 200 mg wiegen Probe (vorgetrocknet bei 105 ° C für 4 h), und es in ein 250 ml Becherglas legen. 5ml einer Mischung zwischen einem Schwefelsäure (TS-241) Testlösung und 50 Essigsäureanhydrid und dann deckt die Uhrglas. Nach dem Erhitzen ein Dampfbad für 20 Minuten auf, kühlen sie auf einem Eisbad, 100ml Wasser und kochen 20min. Nach dem Abkühlen wird die Probe in einen 250 ml Scheidetrichter eine kleine Menge Wasser verwendet wird. 30 sukzessiv verwenden, 25, 20, 15, 10 und 5 ml Chloroform, die Lösung für sechs Mal extrahiert (erstes spülen den Becher). Alle Der Chloroformextrakt wurde in einem zweiten 250m1 Scheidetrichter gesammelt. Waschen Sie die gemischte Extrakt wurde mit 10 ml Wasser. Setzen Sie die Chloroformlösung durch einen Trichter Watte und überträgt es auf einem 150ml vorgewogenen Soxhletkolbens. Verwenden 10ml Chloroform Scheidetrichter und den Trichter zu waschen und in den Extrakt eingearbeitet. Man dampft sie auf einem Dampfbad bis zur Trockne, und dann übertragen, in einem Ofen bei 105 ° C zum Trocknen von 1h. Kühlen Sie es in einem Exsikkator, und gewogen. Verwenden der erhaltenen Menge von sechs Inosit Acetat multiplizieren mit 0,4167, nämlich der entsprechenden Menge von Inositol (C6H12O6).

Funktion:

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.
