Title
(EN) METHOD FOR OBTAINING DOCOSAHEXAENOIC ACIDETHYL ESTER AND PHARMACEUTICAL COMPOSITIONS COMPRISING STEARIDONIC ACID ETHYL ESTER
(FR) PROCÉDÉ POUR L'OBTENTION D'ESTER ÉTHYLIQUE DE L'ACIDE DOCOSAHEXAÉNOÏQUE ET COMPOSITIONS PHARMACEUTIQUES COMPRENANT DE L'ESTER ÉTHYLIQUE DE L'ACIDE STÉARIDONIQUE
Abstract
(EN) This invention relates to the production of docosahexaenoic acid ethyl ester from a mixture of essential fatty acids ethyl esters in which it is present as a minor constituent. The isolated stearidonic acid is used to prepare pharmaceutical compositions, which are administered to treat inflammatory conditions and to prepare costneceutical compositions for treatment of skin.
(FR) Cette invention porte sur la production d'ester éthylique de l'acide docosahexaénoïque à partir d'un mélange d'esters éthyliques d'acides gras essentiels dans lequel il est présent comme constituant minoritaire. L'acide stéaridonique isolé est utilisé pour préparer des compositions pharmaceutiques, qui sont administrées pour traiter des affections inflammatoires, et pour préparer des compositions cosmétiques pour le traitement de la peau.
