Determination of Enantiomeric Composition of Partly Racemized Carotenols

Method for determining enantiomeric composition of various racemized carotenols by converting them into diastereomeric esters with subsequent analysis have been studied.Diastereomeric esters of (-)-camphanic acid with carotenols other than α-ketols could not be separated by HPLC.No separation was achieved for diastereomeric esters of methoxytrifluoromethylphenylacetic acid (MTPA). 1H NMR analysis in the presence of Eu(fod)3 of diastereomeric MTPA esters allowed quantitative determination of the enantiomeric composition of carotenols with 2-hydroxy-β- and 3-hydroxy-β-type end groups.
