Beta-carotene is a strong red-orange organic pigment that is abundant in mushrooms, plants, and fruits. It is one of the members of carotenes, which are terpenoids (isoprenoids) that are synthesized biochemically
from eight isoprene units and have 40 carbons.
Beta-carotene is the most common form of carotene in
plants. Plant carotenoids are the primary dietary source of pro-vitamin B worldwide, and beta-carotene is the best known pro-vitamin A carotenoid.
Isolation of beta-carotene from fruits rich in carotenoids is usually done
using column chromatography. It can also be extracted from algae rich in beta-carotene.
The separation of β-carotene from a mixture of other carotenoids is based on the polarity of a compound.
Beta-carotene is a non- polar compound, so it separates with a non-polar solvent such as hexane because it is highly conjugated, has a deep color and, as a hydrocarbon without functional groups, is very lipophilic.
