A solvent extraction process for extracting oil containing dihomolinolenic acid from marine macro-algae, since as ascophyllum. Harvested ascophyllum is desalted to a salt content of less than 3% by weight, and dried to a moisture content of less than 5% by weight, and is then chopped into pieces of maximum dimension not exceeding 5 mm. The desalted, dried and chopped ascophyllum is then packed into a cellulose soxhlet thimble (13) and covered with a silica glass wool. The soxhlet thimble (13) is then placed in a vessel (12) of a soxhlet apparatus (11). A solvent reservoir (15) is charged with the solvent, namely, a food grade hexane, and is evaporated from the solvent reservoir (15) and condensed in a condenser (22) above the vessel (12) and is drip-fed into the soxhlet thimble (13) for extracting the oil containing the dihomolinolenic acid from the ascophyllum. The solvent with the extracted oil entrained therein is returned to the solvent reservoir (15) and the process continues until substantially all the oil has been extracted from the ascophyllum. The oil containing the dihomolinolenic acid is then recovered from the solvent by low pressure distillation until the solvent content of the oil containing the dihomolinolenic acid has been reduced to less than 5% by weight. The oil containing the dihomolinolenic acid is then desolvated to remove the remaining solvent therefrom.
