In nature, Î²-carotene is a precursor (inactive form) to vitamin A via the action of beta-carotene 15,15'-monooxygenase. Isolation of Î²-carotene from fruits abundant in carotenoids is commonly done using column chromatography.It can also be extracted from the beta-carotene rich algae, Dunaliella Salina.The separation of Î²-carotene from the mixture of other carotenoids is based on the polarity of a compound. Î²-Carotene is a non-polar compound, so it is separated with a non-polar solvent such as hexane.arotene is the substance in carrots, pumpkins and sweet potatoes that colors them orange and is the most common form of carotene in plants.
