Methods for preparation of lycopenes from c15-wittig salts and methods for purification of high all-e containing and high 6z containing c15-wittig salts

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.

What is claimed is: 
     
         1 . A product of lycopene crystals produced directly from a chemical synthesis process and containing an all-E content of at least 95% (HPLC area %). 
     
     
         2 . The product according to  claim 1 , formulated as one selected from the group consisted of a tablet, a capsule, emulsion water and an oil. 
     
     
         3 . A product of lycopene crystals produced directly from a chemical synthesis process and containing a 5Z content of at least 95% (HPLC area %). 
     
     
         4 . The product according to  claim 3 , formulated as one selected from the group consisted of a tablet, a capsule, emulsion water and an oil.
