Seeds of Atriplex griffithii, Haloxylon ammodendron, Salicornia europaea and Salsola yazdiana were analyzed to determine their potential as sources of edible oil. The quantity of total oil varied from 13.8% in Atriplex griffithii to 20.9% in H. ammodendron. The proportion of unsaturated fatty acids were higher (62-73.8%), with the highest values of α-linoleic acid (18.6%), linoleic acid (28.6%) and oleic acid (19.7%) in the seeds of A. griffithii, H. ammodendron and S. europaea, respectively. Results of physicochemical evaluation of the extracted oils ranged as follows: iodine values, 99.8-106.5 (g I2/100 g); saponification value, 188-283 (mg KOH/1g of oil); peroxide value, 9-13 (meq/kg) and refractive index, 1.4750- 1.4761. Amongst these oilseeds, S. europaea (containing 73.8% unsaturated fatty acids but not erucic acid) was the highest in quality for human consumption followed by H. ammodendron.
