ABSTRACT:
A novel process for the preparation of highly purified carotenoids from plant extracts, especially the marigold flower extracts, is disclosed. The process includes the formation, isolation and purification of carotenoids, primarily lutein and zeaxanthin, at lower temperatures with the use of at least a polar solvent and at least a non-polar solvent. The highly purified carotenoids so obtained are useful for human consumption, such as nutritional supplements and pharmaceuticals.
