Process for obtaining 3'-epilutein

摘要

A process for obtaining 3'-epilutein, by epimerization of a lutein-containing extract with an aqueous solution of a strong organic acid which is slowly added under agitation at room temperature, in the presence of an organic aprotic media, to obtain 3'-epilutein(crystals) in a solution which is neutralized with an alkali and extracting the 3'-epilutein from said solution by means of an organic media, then washing and drying the crystals and purifying them by chromatography by means of a chromatography column.
