    Abstract: Substantially pure stearidonic acid is isolated from a mixture of polyunsaturated fatty acids by fractionating at 25% to 35% by weight solution of fatty acids by high-performance reverse-phase liquid chromatography using a mobile phase of 75% to 95% by weight methanol and 25% to 5% by weight water. The isolated stearidonic acid is used to prepare pharmaceutical compositions which are administered to treat cardiovascular and thrombo-embolic diseases associated with platelet aggregation.

    Abstract: A mixture of fatty acids, including derivatives thereof, containing polyunsaturated fatty acids, including derivatives thereof, are reacted with urea in solution. The reaction medium is pumped through at least one scraped-surface heat exchanger for cooling the reaction medium for forming a dispersion of a solid inclusion complex and a liquid phase. The liquid phase which contains a fraction enriched with polyunsaturated fatty acids, including derivatives thereof, then is separated from the inclusion complex.
