The invention relates to a method for the selective extraction of functionalised fatty acid esters from seeds of oleaginous plants, wherein said method includes : a) at least one step of extracting fatty acid esters that comprises simultaneously feeding into a reactor containing said seeds a light anhydrous alcohol, a basic catalyst and an extraction solvent non-miscible with said light alcohol and in which said functionalised fatty ester is not soluble in order to obtain a mixture of esters and glycerol; b) and at least one step of selectively extracting hydroxylated fatty acid esters by feeding into the reactor said extraction solvent in a backflush direction relative to the light alcohol in order to obtain an alcohol phase enriched with fatty acid esters, a glycerol phase and a cake. The invention can be used for obtaining a fraction having a high concentration of hydroxylated or epoxydised functionalised fatty acid esters, and a solvent phase containing the other non-functionalised fatty acid esters directly from the seeds of oleaginous plants.

La présente invention concerne un procédé d'extraction sélective d'esters d'acides gras fonctionnalisés, à partir de graines de plantes oléagineuses. Le procédé selon l'invention comprend: a) au moins une étape d'extraction des esters d'acides gras consistant en l'introduction simultanée dans un réacteur contenant lesdites graines, d'un alcool léger anhydre, d'un catalyseur basique et d'un solvant d'extraction non miscible avec ledit alcool léger et dans lequel ledit ester d'acide gras fonctionnalisé n'est pas soluble, conduisant à l'obtention d'un mélange d'esters et de glycérol, et b) au moins une étape d'extraction sélective des esters d'acides gras hydroxylés par introduction dans le réacteur dudit solvant d'extraction à contre-courant de l'alcool léger, conduisant à l'obtention d'une phase alcool enrichie en esters d'acides gras d'une phase glycérol et d'un tourteau. Ce procédé permet d'obtenir une fraction concentrée en esters d'acides gras fonctionnalisés, hydroxylés ou époxydés, d'une phase solvant contenant les autres esters d'acides gras non fonctionnalisés, directement à partir des graines de plantes oléagineuses.
