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.
