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.

Obsah Analýza: Přesně se naváží 200 mg vzorku (předem suší při teplotě 105 ° C po dobu 4 hodin), a umístit do 250 ml kádinky. Přidat 5 ml směsi mezi jednou kyselinou sírovou (TS-241) testovací roztok a 50 anhydridu kyseliny octové, a potom pokrytí sklíčkem. Po zahřívání na parní lázni po dobu 20 minut, ochladí se na ledové lázni, přidá se 100 ml vody, a vaří se 20 min. Po ochlazení, přenos vzorku do 250 ml dělící nálevky pomocí malého množství vody. Postupně použití 30, 25, 20, 15, 10 a 5 ml chloroformu k extrakci řešení šestkrát (první vyprázdnění kádinku). Všechny Chloroformový extrakt se oddělí ve druhém 250m1 dělicí nálevky. Promyjte smíšený extrakt se 10 ml vody. Položte Chloroformový roztok přes vatu nálevkou a přenést je do 150 ml předem zvážené Soxhletově baňky. Pomocí 10 ml chloroformu, k mytí dělicí nálevky a nálevku a začleněny do extraktu. Odpaří se do sucha na vodní lázni, a pak převést v peci při teplotě 105 ° C po dobu sušení 1H. Ochladí se v exsikátoru a zváží. Použít se získané množství šest inositol acetát vynásobit 0.4167, a to odpovídajícím množstvím inositolu (C6H12O6).

Funkce:

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.
