Thermal stereoisomerization of all-(E)-.BETA.-carotene: (Z)-.BETA.-carotenes and electrocyclized .BETA.-carotenes.

open access: yesJournal of Nutritional Science and Vitaminology, 1983
Thermal isomerization of synthetic all-(E)-beta-carotene yielded a multi-component mixture composed of more than sixteen (Z)-beta-carotenes and two thermo-cyclized isomers. They were separated and purified by high-performance liquid chromatography. Ten of these were characterized by spectroscopic methods as four mono-(Z)-, five di-(Z)-, and one tri-(Z)-
