Vitamin A/E HPLC Assay

HPLC assay intended for the quantitative determination of vitamin A and E.


Vitamin A and E belong to the fat-soluble vitamins and can be stored in the fatty tissue over a longer period of time.

Both an over- and an undersupply of vitamins A and E can cause issues. Vitamin A (retinol) is essential for the visual process and keeps the skin and mucous
membranes healthy. A deficiency of vitamin A can therefore have an impact on vision, especially during transitions from light to dark. A severe vitamin A deficiency can lead to
blindness. Too much vitamin A however, can also have a pathological effect and cause headaches, skin changes, liver damage, painful skeletal changes and damage to the fetus.

Vitamin E (tocopherol) is a natural antioxidant that protects unsaturated fatty acids from oxidation. It intercepts the radicals before they can have a destructive effect on the cell.
A deficiency of vitamin E showed damage to the musculature, nervous system and heart, liver and reproduction in animal experiments. In humans, such effects have not been observed. Vitamin E can be stored in large quantities in fatty tissue. An undersupply can occur due to impaired fat digestion or absorption.
