Identification and cultivation of new oilseeds is an important step in supplying the oil needed in the country. Regarding the vastness of saline areas in the country, the cultivation and exploitation of salinity-resistant plants under saline conditions of both water and soil can be an appropriate option in the field of production and extraction of oils from salinity-resistant plants. The aim of this study was to determine the percentage of extractable oil and the compounds of fatty acids in two halophyte species Salicornia europaeae and Halocnemum strobilaceum on the shores of Lake Urmia. For this purpose, the seeds of the species were collected in autumn of 2016. Fatty acids were extracted by solvent. The solvent-oil mixture was separated by rotary vacuum distiller, and after methyl ester preparation and injection into the gas chromatography (GC), fatty acids were analyzed. To identify the fatty acids, a standard mixture of fatty acids (Sigma Co.) and their inhibition times were used. Data were analyzed by SPSS software using independent t-test. The mean oil yields of two species of S. europaeae and H. strobilaceum was obtained 18.58 and 9.28%, respectively. In total, 12 fatty acids including lauric acid (C12: 0), merisitic acid (C14: 0), myristoleic acid (C14: 1n5), palmitic acid (C16: 0), palmitoleic acid (C16: 1n7), stearic acid (C18: 0), oleic acid (C18: 1n9), linoleic acid (C18: 2n6cis), α-linolenic acid (C18: 3n3), g-linoleic acid (C18: 3n6), and arachidic acid (C20: 0) were recorded in the profiles of these two species. Linoleic acid was the most major unsaturated fatty acid in S. europaeae and H. strobilaceum, at 56 and 54.7%, respectively. Palmitic acid was also predominant saturated fatty acid in S. europaeae and H. strobilaceum, at 11.4 and 9.7%, respectively. The results showed that according to the oil yield (18.58%) and percentage of saturated and unsaturated fatty acids identified, S. europaeae seeds could be evaluated as a source of edible oil.

Given the extent of saline lands in Iran, cultivation and utilization of halophytes and salt tolerant species under the condition that both water and soil are saline could be a viable option in production and extraction of vegetable oils from halophytes and salt tolerant species. The aim of this study was to investigate the potential of Suaeda fruticosa (L.) Forssk. and Salicornia herbacea L. as a source of edible oil as well as qualitative and quantitative analysis of the oil. For this purpose, the seeds of Suaeda fruticosa and Salicornia herbacea were collected from saline soils of Garmsar and Kal-e Shur Desert Research Station. In this study, a random sampling was done by replicated plots. The extraction of fatty acids was performed by solvent in Soxhlet method, and GC was used to analyze the fatty acids. The average oil yield was calculated to be 30.76 and 13.88% in Suaeda fruticosa and Salicornia herbacea, respectively. According to the results, in both species, palmitic acid and linoleic acid were identified as the major saturated and unsaturated fatty acids, respectively. Our data clearly indicate that the seeds of halophyte Suaeda fruticosa could be used as a source of oil for human consumption.

The use of analgesic and anti-inflammatory medications is indispensable in clinical medicine. On the other hand, the increasing use of chemical drugs has several side effects that can sometimes be more dangerous than the disease itself. Therefore, research on the medicinal properties of plants to explore the effects of drugs with similar or even better than chemical drugs with fewer side effects is of great importance. In this research, analgesic and anti-inflammatory effects of Thymus daenensis Celak were investigated. For this purpose, 75 male mice weighing approximately 20-30 g were divided into 15 groups of 5 mice each. Writhing and formalin tests were applied to study analgesic effects and Xylene test was used to examine the anti-inflammatory effects. Extract at doses of 400, 600 and 800 mg/kg was tested. Saline solution and morphine (10 mg/Kg) were used in analgesic experiment and dexamethasone (10 mg/ kg) was used for anti-inflammatory experiment as positive group. Data were analyzed by SPSS software and mean comparisons were performed by Duncan’s Multiple Range Tests. According to the results, ethanolic extract of Thymus daenensis showed analgesic effects in Writhing test. Analgesic effects were not significant in the first phase of formalin test but it was significant in the second phase. Ethanolic extract of Thymus daenensis showed antiinflammatory effects at dose of 800 mg/kg-1. The conclusion is that analgesic effects of ethanolic extract of Thymus daenensis probably are caused by para cymene, -β-caryophyllene, carvacrol and especially thymol. Increasing doses and study on anti-inflammatory effects through other tests are needed for final confirmation of anti-inflammatory effects of Thymus daenensis.
