The invention relates to a method of combined cell digestion and extraction of oil-containing seeds having an oil content of &#x3e;30% by mass, wherein production of a slurry from the oilseeds and ethanol is followed by a combination cell digestion with a subsequent ethanolic extraction, wherein the smaller portion of the oil of the oilseed and the alcohol-soluble constituents present therein are dissolved in the ethanol in accordance with the dissolution capacity of the ethanol for the oil and the alcohol-soluble constituents, a greater portion of the oil is displaced from the seed cells by the ethanol, forming a free oil phase in the ethanol. The free oil phase is removed and, according to the invention, has semi-raffinate quality, reducing the complexity of refining as an advantage of the method of the invention.
