  • Process for the enrichment with .DELTA.6 fatty acids of a mixture of fatty acids
    Patent number: 4776984
    Abstract: For the selective enrichment with fatty acids, of which the first double bond is in the 6 position, of a starting material containing fatty acids of which the first double bond is in the 6 or 9 position, the starting material is treated with a saturated solution of urea in methanol with predetermined ratios of fatty acids to urea so as to separate the fatty acids, other than the .DELTA.6 polyunsaturated fatty acids in the form of an insoluble inclusion complex.The enriched fractions obtained may be treated by high-performance liquid chromatography to isolate substantially pure .gamma.-linolenic acid.The enriched fractions, optionally recombined with glycerol, may be used in medicaments and in nutritive compositions or may even serve as starting product in the synthesis of dihomo-.gamma.-linolenic acid.

  • Nutritive compositions containing fatty substances and a process for the preparation thereof
    Patent number: 4703060
    Abstract: The oil of pips of fruits of the Ribes genus is an abundant, cheap source of .gamma.-linolenic acid.It is extracted using solvents from dried and ground residues from the production of juices, preserves and jellies or brandies, liqueurs and schnapps of fruits, such as blackcurrant, redcurrant or gooseberry. According to a preferred embodiment, the residues are treated with ethanol before being extracted with hexane in order to free the oil from most of the free fatty acids, waxes, colorings and odorous compounds.The refined oil is a valuable ingredient in cosmetic, dermatological, dietetic and pharmaceutical compositions.
