A method of chromatographic isolation of Vitamin E isomers ((-tocopherol, (-tocopherol, (-tocopherol, (-tocopherol, (-tocotrienol, (-tocotrienol, (-tocotrienol, and (-tocotrienol) from Vitamin E- comprising compounds, said method including the steps of introducing the substances, which form the source of the Vitamin E isomers, onto selective adsorbents to effect adsorption of Vitamin E isomers and subsequently, effecting an individual desorption of the adsorbed Vitamin E isomers, wherein the adsorption and/or desorption of the Vitamin E isomers are carried out under a supercritical fluid environment.
L'invention concerne une méthode d'isolation chromatographique d'isomères de vitamine E ((-tocophérol, (-tocophérol, (-tocophérol, (-tocophérol, (-tocotriénol, (-tocotriénol, (-tocotriénol, et (-tocotriénol) à partir de composés comprenant la vitamine E. La méthode consiste à introduire les substances, qui forment la source des isomères de vitamine E, dans des adsorbants sélectifs pour effectuer l'adsorption des isomères de vitamine E et, par la suite, la désorption de chacun des isomères de vitamine E adsorbés. L'adsorption et/ou la désorption des isomères de vitamine E sont effectuées dans un milieu fluide supercritique.
