Diastereomeric resolution of carotenoids : IV. Carotenoids with a 4-hydroxy-β-end group

A method is described for the diastereomeric resolution of carotenoids with a 4-hydroxy-β-end group, viz., β-isocryptoxanthin (β,β-caroten-4-ol), isozeaxanthin (β,β-carotene-4,4′-diol) and 4′-hydroxyechinenone (4′-hydroxy-β,β-caroten-4-one). The separation of each carotenoid into individual optical...

Description
Summary:A method is described for the diastereomeric resolution of carotenoids with a 4-hydroxy-β-end group, viz., β-isocryptoxanthin (β,β-caroten-4-ol), isozeaxanthin (β,β-carotene-4,4′-diol) and 4′-hydroxyechinenone (4′-hydroxy-β,β-caroten-4-one). The separation of each carotenoid into individual optical isomers was achieved by high-performance liquid chromatography using a Chiralcel OD [cellulose tris(3,5-dimethylphenylcarbamate) coated on silica gel] chiral resolution column after conversion to the corresponding benzoates.
