Process for the fractionation of seeds from oleaginous plants

A process for the fractionation of seeds of oleaginous plants of the Asteraceae family in oil, solid residue and active substances comprising the steps of:

• (a) subjecting said seeds to at least one mechanical pressing operation, removing at least a portion of the oil and obtaining a first residue;
• (b) subjecting said first residue to extraction with a polar organic solvent and separating the remaining solid residue from the resulting liquid phase comprising oil and extracted active substances;
• (c) separating the active substances and oil from said liquid phase of step b),
• wherein the extraction of step b) is performed at temperatures above ambient temperature and below or equal to the boiling point of the solvent.
