Datasheet:

Vitamin E (vitamin E) is a kind of natural fat soluble antioxidant, which can block the peroxidation of

unsaturated fatty acids, maintain the integrity and normal function of the membrane of unsaturated fatty

acids, and remove superoxide anion free radicals. It has the functions of anti-aging, preventing hemolytic

anemia and so on. It has a high application value in medicine, cosmetics, health products and food

industry.

Fe³⁺is reduced to Fe²⁺by VE. Fe²⁺can react with 1,10-Phenanthroline to produce colored complex, which

has a characteristic absorption peak at 510 nm.

Reagents and Equipment Required but Not Provided.

Spectrophotometer, scales, desktop centrifuge,

mL glass cuvette, adjustable pipette,

mortar/homogenizer, vortex shaker, absolute ethanol, n-heptane, distilled water and EP tube.
