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.

Innholdsanalyse: Nøyaktig veie 200 mg prøve (for-tørket ved 105 ° C i 4 timer), og plassere den i et 250 ml begerglass. Legg 5 ml av en blanding mellom ett svovelsyre (TS-241) testløsning og 50 eddiksyreanhydrid, og deretter dekke urglass. Etter oppvarming på et dampbad i 20 min, avkjøles den på et isbad, tilsett 100 ml vann, og kok 20 min. Etter avkjøling overføres prøven i en 250 ml skilletrakt ved hjelp av en liten mengde vann. Suksessivt bruker 30, 25, 20, 15, 10 og 5 ml kloroform for å ekstrahere løsningen for seks ganger (først skylle begerglasset). Alle kloroformekstrakten ble samlet i en andre 250m1 skilletrakt. Vask den blandede ekstrakt med 10 ml vann. Sett kloroformoppløsningen gjennom en trakt vatt og overføre den til en 150 ml på forhånd veiede Soxhlet-kolbe. Bruk 10 ml kloroform for å vaske skilletrakt og trakten, og innlemmet i ekstraktet. Fordampe det til tørrhet på et dampbad, og deretter overføre den i en ovn ved 105 ° C for tørking i 1 time. Avkjøl den i en eksikkator, og veie det. Bruk den oppnådde mengden av seks inositol acetat multiplisere med 0,4167, nemlig den tilsvarende mengde inositol (C6H12O6).

Funksjon:

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.
