TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Method: In (E), (A) is present in a 1-4C alcohol (preferably ethanol) containing solution (preferably an aqueous alcohol containing solution). The solution of (E), obtained form the urea fractionation of (A), is prepared by dissolving the solid urea complex obtained from the urea fractionation of (A), or is obtained following the trans-esterification of lipid(s) with an alcohol (preferably ethanol). The solution is contacted with supercritical CO2 at 308 - 353 K, and a pressure of 150 - 500 (preferably 150 - 300) bar. The solution and near critical fluid are contacted using a static mixer; the urea containing precipitate is obtained as an aqueous solution, and further contains a colored compound (preferably chlorophyll derivative). The pressure of the near-critical fluid phase is reduced in at least two steps to recover at least two fractions containing (A). The extraction is carried out as a continuous process where the (P) and (F) are continuously removed from an extraction vessel without reducing the pressure of the vessel. The process further includes washing (F) phase in a high-pressure water wash column before reducing the pressure of (F) to recover (A). (E1) further involves winterising the lipid hydrosylate solution prior to combining the hydrosylate solution with urea (preferably solid urea or its solution, especially aqueous ethanol solution of urea). In (E2) the solvent or solvent mixture is ethanol or aqueous ethanol, and the oil solution is winterised before combining with urea. (E1) and (E2) further involves dissolving the solid urea/lipophilic compound complex in a solvent or solvent mixture containing 1-4C alcohol (preferably ethanol or aqueous alcohol) to form a solution prior to contacting with a near-critical fluid.Preferred Components: (A) is selected form derivatives of triglycerides or glycerol ethers, or nonglyceride lipophilic compounds (preferably fatty acids, fatty acid 1-4C alcohol esters, fatty acid amines, fatty acid amides, alkoxyglycerol ethers, fatty alcohols (all including unsaturated or polyunsatuated at least 1-18C longer fatty acid or their derivatives), fat soluble vitamins, sterols, wax esters, carotenoids, hydrocarbons, saturated fatty acids, monounsaturated fatty acids or alkoxyglyceryl ethers (preferably polyunsaturated fatty acid or its derivative (preferably all cis- 5,8,11,14, 17-eicosapentaenoic acid; all cis-4,7,10,13,16,19-docosahexaenoic acid; 6,9,12-octadecatrienoic acid, 9,12,15-octadecatrienoic acid, 9,11-octadecadienoic acid or their derivative), a fat soluble vitamin (preferably vitamin A, vitamin D, vitamin E or their ester), or a carotenoid (preferably astaxanthine, beta-carotene or lycopene), a hydrocarbon (preferably squalene) or oleic acid). The near-critical fluid is selected from ethane, ethylene, propane, propylene, butane, fluorinated 2-3C hydrocarbon, dimethylether, and/or partially or fully fluorinated analogues of dimethylether (preferably fluorinated 2-3C hydrocarbon, especially 1,1,1,2-tetrafluoroethane). The non-glyceride component is selected from squalene, vitamin E or carotenoid. The oil is selected from olive oil deodoriser distillate, soya oil deodoriser distillate or saw palmetto oil.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The near-critical fluid is selected from supercritical CO2, liquid CO2, nitrous oxide and/or sulfur hexafluoride (preferably supecritical CO2 or liquid CO2, especially supercritical CO2)    TECHNOLOGY FOCUS - BIOLOGY - Preferred Component: The lipid hydrosylate solution is obtained from the hydrolysis of fish, animal or plant oil (preferably fish oil or seed oil). The seed oil is selected from borage, blackcurrant, evening primrose, Echium, Lunariurn, meadowfoam, saw palmetto, pumpkin or Biota orientalis. For (E2) the oil is selected from olive oil deodoriser distillate, soya oil deodoriser distillate and saw palmetto oil. ACTIVITY - Cytostatic; Cardiovascular-Gen.; Antiinflammatory.    MECHANISM OF ACTION - None given.    EXAMPLE - Ling liver oil (1 kg) containing cis-4,7,10,13,16,19-docosahexaenoic acid (DHA) (10.8%) and polyunsaturated fatty acid (PUFA) (24%) was hydrolysed in ethanol/water using potassium hydroxide. The pH of the final solution was 14. A saturated urea solution was prepared by mixing urea (1 kg) into 90% by mass ethanol/water (3 l) and heated to 60 degrees C. This solution was then mixed with the fatty acid hydrosylate solution, slowly cooled, frozen overnight, and then removed the next day. The solution was filtered under gravity to separate the solid urea complex from the filtrate. The filtrate (6.74 kg) was then pumped at 200 bar, at an average mass flow of 1.8 kg per hour. The filtrate was mixed with supercritical carbon dioxide (CO2) at 200 bar and 40 degrees C before entering the precipitation chamber. The supercritical carbon dioxide was pumped at a rate of 12.3 kg per hour. A precipitate consisting of water, urea, glycerol and phospholipid derivatives was obtained from the bottom of the precipitation chamber at a rate of 0.61 kg per hour. The supercritical carbon dioxide and dissolved ethanol and free fatty acid (FFA) passed through two separation stages by sequential pressure reduction. The separators were held at 110 bar and 60 bar respectively. The first separation yielded, free fatty acids (FFA) (18-22C monounsaturated fatty acids (MUFA) and polyunsaturated fatty acids (PUFA) containing docosahexanoic acid (DHA) (22.7% by mass) and PUFA (40.8% by mass)) (70 g) after separation of ethanol. The second separation yielded FFA (16-22C MUFA and PUFA containing DHA (19.2% by mass) and PUFA (35.8% by mass) (293 g). The total recovery of FFA was 86%.
