ABSTRACT:
A process for separating the various members of a tocopherol homologue mixture to obtain fractions of the separate tocopherol homologues. The isolation of the various tocopherol homologues is accomplished by selective deacylation of tocopheryl esters followed by separation of the esters from the free tocopherols.
