イノシトール

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番号：87-89-8

コンテンツ分析：正確（4時間105℃で予備乾燥した）200 mgのサンプルを秤量し、250ミリリットルのビーカーにそれを置きます。 1つの硫酸（TS-241）試験溶液および50の無水酢酸の混合5mlのを追加し、時計皿を覆います。 20分間蒸気浴上で加熱した後、水100ml、及び沸騰の20分を追加し、氷浴上で冷却します。 冷却後、少量の水を用いて分液漏斗250ml中に試料を移します。 連続6回の解を抽出するためにクロロホルムの30、25、20、15、10及び5 mLのを使用（第1のビーカーを洗い流します）。 全てのクロロホルム抽出物を第二250m1分液漏斗中に集めました。 10mlの水と混合した抽出物を洗浄します。 漏斗コットンウールを通してクロロホルム溶液を入れて、150ミリリットル予め秤量したソックスレーフラスコに移します。 分液漏斗及び漏斗を洗浄するために10mlのクロロホルムを使用し、抽出物中に組み込みます。 蒸気浴上で乾固し、それを蒸発させ、次いで1時間の乾燥を105℃のオーブンでそれを転送します。 デシケーター中でそれを冷却し、それを量ります。 0.4167によって6回のイノシトール酢酸乗算、イノシトールのすなわち対応する量（C6H12O6）の得られた量を使用します。

関数：

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.
