Content, composition and characteristics of Myrtle berries seed oil were studied. Myrtle berries pulp was screened and the seed washed, dried and grinded in a Thomas mill (20 mesh). Seed oil content was determined in a soxhlet apparatus after chloroform extraction during 5 hours. A cold extraction with hexane during 18 hours was done to determine composition, physical and chemical characteristics. Seed oil content was nearly 16%. Physical and chemical characteristics were similar to other vegetable edible oil. Refractive index (20 deg C) 1.4765; specific weight (15 deg C) 0.913. Free fatty acid, as % oleic, 0.25%; iodine number, 160,9; saponification number, 196.4. Gas chromatography revealed a high degree of insaturation, 93.1%, with a linoleic acid content of 85.8% followed by oleic acid, 7.3% and palmitic acid, 5.6%. Due to its high content of fatty acid linoleic, essential nutrient for the prostaglandin synthesis, the making-up of cell membranes, the defense mechanisms, the growth and other physiologic and biochemical processes related to tissue regeneration, Myrtle berries seed oil could be a good potential source of tissue regenerating oil
