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.

Kufutwa katika maji (25 ° C, Gramu 14 / 100ml; 60 ° C, 28g / 100ml), kidogo mumunyifu katika ethanol, asidi asetiki, ethilini glikoli na GLYCEROL, hakuna katika etha, asetoni na kloroform. Imara katika hewa; Imara kwa joto, asidi na alkali, lakini ni RISHAI.

CAS No: 87-89-8

Uchambuzi Content: usahihi na uzito wa 200 mg sampuli (kabla ya kavu katika 105 ° C kwa 4h), na mahali ndani ya kopo 250ml. Kuongeza 5ml ya mchanganyiko kati ya asidi sulfuriki moja ufumbuzi (TS-241) kupima na 50 asetiki anhidridi, na kisha kufunika kuangalia kioo. Baada ya inapokanzwa juu ya umwagaji mvuke kwa 20min, baridi kwenye barafu kuoga, kuongeza maji 100ml, na jipu 20min. Baada ya baridi, kuhamisha sampuli katika mL 250 kutenganisha faneli kwa kutumia kiasi kidogo cha maji. Mfululizo kutumia 30, 25, 20, 15, 10 na 5 ya mililita ya klorofomu ili kutoa ufumbuzi kwa mara sita (kwanza kuvuta kopo). All klorofomu dondoo ilikusanywa katika pili 250m1 kutenganisha funnel. Osha dondoo kuchanganywa na 10ml ya maji. Weka klorofomu ufumbuzi kwa njia ya faneli pamba na uhamisho kwa 150ml kabla ya vunja Soxhlet chupa. Matumizi 10ml ya klorofomu kuosha kutenganisha funnel na faneli, na kuingizwa katika dondoo. Kuyeyuka kwa ukavu juu ya umwagaji mvuke, na kisha kuhamisha katika tanuri katika 105 ° C kwa kukauka saa 1. Baridi katika desiccator, na uzito wa jambo hilo. Matumizi kupatikana kiasi cha sita inositoli acetate zidisha na 0.4167, yaani kiasi sambamba ya inositoli (C6H12O6).

kazi:

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.
