Abstract
The present invention relates to methods for preparation of lycopenes, especially to lycopenes with high all-E contents or high 6Z contents from C15-Wittig slats mixtures.(with high all-E-contents and high 6Z-contents, respectively). C15-Wittig slats mixtures are purified and 6Z-C15-Wittig salts are extracted from the mixtures. The extracted 6Z-C15-Wittig salts are, used in the synthesis of lycopenes with high 6Z contents and the residues are used in the synthesis of lycopenes with high All-E contents.
IPC Classes ?
- C07C 1/34 - Preparation of hydrocarbons from one or more compounds, none of them being a hydrocarbon starting from compounds containing hetero atoms other than, or in addition to, oxygen or halogen reacting phosphines with aldehydes or ketones, e.g. Wittig reaction
- C07F 9/54 - Quaternary phosphonium compounds
- C07C 11/21 - AlkatrienesAlkatetraenesOther alkapolyenes

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.
IPC Classes ?
- C07C 35/21 - Compounds having at least one hydroxy or O-metal group bound to a carbon atom of a ring other than a six-membered aromatic ring polycyclic, at least one hydroxy group bound to a non-condensed ring
