The invention relates to a method for obtaining natural oils from plant constituents, said method being essentially carried out using compressed C2-C4 hydrocarbons. Residues from the crop and fruit treatment, especially from the treatment of pips and berries, are used as starting materials. Unlike previous extraction methods using organic solvents, the inventive method can be economically carried out on the basis of low pressures and reduced extraction agent throughputs. Preferred extraction agents are ethane, propane, butane and the mixtures thereof, the extraction itself being carried out in batches at pressures of < 50 mPa and temperatures of < 70 ~C, with an extraction agent throughput of between 4 and 20 kg/kg of starting materials. The extracted oils are outstandingly suitable for flavouring preparations and cosmetic formulations, especially for the care and treatment of the skin.

L'invention concerne un procédé pour obtenir des huiles naturelles à partir d'ingrédients végétaux, ce procédé étant essentiellement effectué à l'aide d'hydrocarbures C2-C4 comprimés. Des résidus issus du traitement de fruits, en particulier du traitement de pépins et de baies, sont utilisés en tant que matériaux de départ. Contrairement aux procédés d'extraction précédents exécutés à l'aide de solvants organiques, le procédé selon l'invention peut être effectué de manière économique sur la base de faibles pressions et d'agents d'extraction à rendement réduit. Les agents d'extraction préférés sont l'éthane, le propane, le butane, et leurs mélanges, l'extraction étant réalisée par lots, également à des pressions < 50 mPa et des températures = 70 °C pour un rendement d'agent d'extraction compris entre 4 et 20 kg par kg de matériau de départ. Les huiles extraites conviennent remarquablement bien pour produire des préparations aromatiques et cosmétiques, et surtout pour soigner et traiter la peau.
