α-Carotene exhibits provitamin A (retinal/retinol/retinoic acid) activity that is necessary for enhancing ocular health. It also shows anti-oxidant, and anti-cancer activities and promotes the function of the immune system. α-Carotene has been studied as an important factor in reducing the risk of cardiovascular diseases.
General description
α-Carotene is usually associated with β-carotene in many fruits and vegetables and belongs to the carotenoid family. It is found in higher concentrations of orange carrots, pumpkins, sweet potatoes, and apricots.

A carotenoid purification method with dual-mode countercurrent chromatography (CCC) for β-carotene, α-carotene and lutein from a fresh carrot extract was developed. The fluorinated liquid benzotrifluoride (IUPAC name: (trifluoromethyl)benzene) was used as a novel modifier in the non-aqueous ternary solvent system
