Vitamin E Chemical Properties,Uses,Production

Chemical Properties

1mg = 1.1 IU

Uses

An antioxidant that protects cell membrane lipids from oxidative damage

Purification Methods

Dissolve dl--tocopherol in anhydrous MeOH (15mL/g) cool to -6o for 1hour, then chill in a Dry-ice/acetone bath; crystallisation is induced by scratching with a glass rod. The dl--acetate [52225-20-4] (see DL-vitamin E actetate below) is a viscous yellow liquid with m -7o, b 184o/0.01mm, 224o/0.3mm, d 4 20 0.953, n D 20 1.496. It is used as a standard for Vitamin E activity where the unit of activity is attained with 1mg of pure dl--acetate. [Friedrich “Vitamins” Water de Guyter Publ, Berlin 1988, Beilstein 17/4 V 168.]
