The invention relates to a method for the solid/liquid extraction of an oil or butter, particularly having a high unsaponifiable content, contained in at least one solid vegetable matter or a micro-organism. The method includes at least the following steps: solid/liquid extraction of at least one solid vegetable matter or a micro-organism using a first solvent system comprising a concentration of solvent selected from among fluorinated aromatic solvents, particularly trifluorotoluene (BTF) and hexafluorobenzene (BHF), tert-butyl ethers, particularly 2-ethoxy-2-methylpropane, also known as ethyl-tert-butyl-ether (ETBE), and 2-methoxy-2-methylpropane or methyl-tert-butylether (MTBE), solvents comprising at least one silicon atom, particularly hexamethyldisiloxane (HMDS) and tetramethylsilane (TMS), methyl-tetrahydrofuran (MeTHF), and mixtures thereof, representing at least 50 vol.-% in relation to the total volume of the solvent system; and, optionally, recovery of a fraction comprising the oil or butter, particularly unsaponifiable enriched. The invention also relates to an unsaponifiable fraction, oil or butter obtained using this method and to compositions containing said oil or fraction.
