         20 . An oil extracted from a solid vegetable matter or a micro-organism, comprising at least 1% by mass of unsaponifiable compounds initially present in the solid vegetable matter or micro-organism. 
     
     
         21 . The oil according to  claim 20 , wherein said oil is devoid of solvents classified in EU1 CMR list, EU2 CMR list and/or the US CMR list. 
     
     
         22 . The oil according to  claim 20 , wherein the solid vegetable matter is obtained from soybean, rapeseed, corn, sunflower, sesame, lupin, cotton, coconut, olive, avocado, cocoa, illipe, shea, palm kernel, peanut, copra, linseed, castor, grape seeds, gourd seeds, blackcurrant seeds, melon seeds, tomato seeds, pumpkin seeds, almond, hazelnut, walnut, evening primrose, borage, safflower, camelina, or poppy seed, or a mixture thereof. 
     
     
         23 . The oil according to  claim 20 , wherein the micro-organism is obtained from macroalgae, microalgae, yeasts, moulds, or bacteria, or a mixture thereof. 
     
     
         24 . An oil obtainable according to a method of solid/liquid extraction, comprising the steps of:
 providing a solid vegetable matter or a micro-organism;   extracting said oil from said solid vegetable matter or a micro-organism by solid/liquid extraction using a first solvent system comprising a concentration of a solvent selected from the group consisting of a fluorinated aromatic solvent, a tert-butyl ether, a solvent comprising at least one silicon atom, and methyl-tetrahydrofuran (MeTHF), or a mixture thereof, representing at least 50% by volume in relation to the total volume of the solvent system; and   recovering a fraction comprising the oil.   
     
     
         25 . The oil according to  claim 24 , wherein the solid vegetable matter is obtained from soybean, rapeseed, corn, sunflower, sesame, lupin, cotton, coconut, olive, avocado, cocoa, illipe, shea, palm kernel, peanut, copra, linseed, castor, grape seeds, gourd seeds, blackcurrant seeds, melon seeds, tomato seeds, pumpkin seeds, almond, hazelnut, walnut, evening primrose, borage, safflower, camelina, or poppy seed, or a mixture thereof. 
     
     
         26 . The oil according to  claim 24 , wherein the micro-organism is obtained from macroalgae, microalgae, yeasts, moulds, or bacteria, or a mixture thereof. 
     
     
         27 . A composition, comprising an oil extracted from a solid vegetable matter or a micro-organism, said oil comprising at least 1% by mass of unsaponifiable compounds initially present in the solid vegetable matter or micro-organism. 
     
     
         28 . A solid vegetable matter from which an oil has been extracted, prepared by a process comprising the steps of:
 providing a solid vegetable matter comprising said oil;   extracting said oil by solid/liquid extraction using a first solvent system comprising a concentration of a solvent selected from the group consisting of a fluorinated aromatic solvent, a tert-butyl ether, a solvent comprising at least one silicon atom, and methyl-tetrahydrofuran (MeTHF), or a mixture thereof, representing at least 50% by volume in relation to the total volume of the solvent system; and   recovering said solid vegetable matter from which an oil has been extracted.   
     
     
         29 . A micro-organism from which an oil has been extracted, prepared by a process comprising the steps of:
 providing a micro-organism comprising said oil;   extracting said oil by solid/liquid extraction using a first solvent system comprising a concentration of a solvent selected from the group consisting of a fluorinated aromatic solvent, a tert-butyl ether, a solvent comprising at least one silicon atom, and methyl-tetrahydrofuran (MeTHF), or a mixture thereof, representing at least 50% by volume in relation to the total volume of the solvent system; and   recovering said micro-organism from which an oil has been extracted.   
     
     
         30 . The oil according to  claim 23 , wherein said micro-organism is  Haematocococcus, Dunaliella, Spirulina , or  Chorella , or a mixture thereof. 
     
     
         31 . The oil according to  claim 24 , wherein said solvent is trifluorotoluene (BTF), hexafluorobenzene (BHF), 2-ethoxy-2-methylpropane, ethyl-tert-butyl-ether (ETBE), 2-methoxy-2-methylpropane, methyl-tert-butylether (MTBE), hexamethyl disiloxane (HMDS), tetramethylsilane (TMS) or methyl-tetrahydrofuran (MeTHF). 
     
     
         32 . The oil according to  claim 26 , wherein said micro-organism is  Haematocococcus, Dunaliella, Spirulina , or  Chorella , or a mixture thereof. 
     
     
         33 . The solid vegetable matter from which an oil has been extracted according to  claim 28 , wherein said solvent is trifluorotoluene (BTF), hexafluorobenzene (BHF), 2-ethoxy-2-methylpropane, ethyl-tert-butyl-ether (ETBE), 2-methoxy-2-methylpropane, methyl-tert-butylether (MTBE), hexamethyl disiloxane (HMDS), tetramethylsilane (TMS), or methyl-tetrahydrofuran (MeTHF), or a mixture thereof.
