Abstract

The aim of this study was to investigate the potential of two halophytes namely: Suaeda aegyptiaca and Halostachys caspica as a source of edible oil as well as quantitative and qualitative oil analysis. For this purpose, the seeds of two halophytes were collected from saline lands of Yazd province, Iran. The extraction of fatty acids was performed by Soxhlet method using a solvent. The analysis of fatty acids was performed by GC. The oil yield obtained from S.aegyptiaca and H caspica was calculated to be 32.99 and 11.97%, respectively. According to the results of oil analysis, Lauric acid (C12), Myristicacid (C14), Palmitic acid (C16) and Stearic acid (C18) were identified as saturated fatty acids in the seed oil of both studied halophytes. Unsaturated fatty acids included Oleic acid (C18: 1), Linoleic acid (C18: 2) and Linolenic acid (C18: 3) and related isomers. The results clearly indicate that the seeds of S.aegyptiaca could be used as a source of edible oil for human consumption. Although the oil yield obtained from H.caspica was almost half that of S.aegyptiaca, however, due to the percentage of saturated and unsaturated fatty acids identified in H.caspica further investigation is required to examine the real potential of this halophyte as a source of edible oil.
