Chemische Eigenschaften

clear light brown viscous liquid

Verwenden

One of the naturally occurring forms of Vitamin E. Most abundant Tocopherol in soybean and corn oils.

Allgemeine Beschreibung

A lipid soluble form of Vitamin E, gamma-Tocopherol is important to human health as an antioxidant and food additive. Vitamin E deficiency, often the result of poor nutrition or low absorption of dietary fat, is monitored in patient serum samples by LC-MS/MS or HPLC.

l?uterung methode

-Tocopherol is purified by distillation at high vacuum and stored in dark ampoules under N2. UV: max at 298nm (A1cm 1% 92.8). It is insoluble in H2O but soluble in organic solvents. The allophanate (used for separating it from its isomers) has m 136-138o, [] D 18 +3.4o (CHCl3). [Baxter et al. J Am Chem Soc 65 918 1943, Emerson et al.
