This experiment was performed in the form of a randomized complete block design with three replications in the spring of 2018 in a research greenhouse located in the city of Urmia. First, the soil sample was analyzed and its physical and chemical properties were measured. Seedlings were transferred to pots after inoculation with azetobarvar-2 and phosphatebarvar-2 biofertilizers. There were 4 plants in each pot. The flowering branches of the plants were harvested at full flowering stage and after drying in the shade essential oil extracted by distillation with water using a Clevenger-type apparatus. Essential oil components were analyzed and identified using GC and GC-MS devices. The constituents of the essential oils were identified by mass spectrum, their retention index (RI) and compared with the retention indices reported in reliable sources. The essential oi yield related to control samples and treatments of azetobarvar-2 and phosphatebarvar-2 was 2, 2.5 and 5 percent, respectively. In total, 29 compounds from the essential oil of this plant were identified, which included the range of 97.22 and 94.98%, and the main constituents of the essential oil, including thymol (65.29, 72.65 and 48.99%), caryophyllene (4.27, 4.29 and 11.92%), eucalyptol (4.95, 3.16 and 8.51%) and borneol (3.66, 3.83 and 4.64%) respectively were for the control sample, Azetobarvar-2 and Phosphatebarvar-2. According to the results of this study, the fertilizer phosphatebarvar-2 treatment may be effective in increasing the percentage of essential oil and its main compounds in Thymus daenensis Celak., while the quantitative and qualitative increase of essential oil under Azotobaror-2 fertilizer treatment was not significant compared to the control.

Hyperlipidemia and high level of serum total cholesterol are risk factors contributing to prevalence and severity of cardiovascular complications like coronary heart diseases. Lamiaceae plants have terpenoids and flavonoids can reduce triglyceride and cholesterol, therefore. This study was done to evaluate the effect of feeding with essential oil of Thymus deanensis Celak. on lipid profile, blood urea and liver enzymes in hyperchlostrolemic male Wistar rats. This experimental study was performed on 36 male Wistar rats. Animals were randomly divided into 6 groups (there were 6 rats in each groups). The groups including control, sham, two groups receiving 200 and 500 ppm Thymus deanensis essential oil and hyperchlostrolemia groups treated with doses of 200 and 500 ppm of Thymus deanensis essential oil. Hyperchlostrolemia was induced by giving high cholesterol (2%) and sweet almond oil (97.5%) diet. The animals were treated for 32 days with essential oil of the thyme. At the end of the 32-day trial, blood sampling was performed. Total cholesterol, triglyceride, urea and alanine aminotransferase (ALT) and aspartate aminotransferase (AST) liver enzymes were measured. The level of ALT and AST in hypercholesterolemia rats were significantly increased in comparison with the control group (P˂0.05). Thymus daenensis essential oil significantly reduced level of triglycerides and cholesterol (P˂0.05). The high dose of Thymus daenensis (500 ppm) essential oil more than a low dose (200 ppm) significantly reduced the level of cholesterol and triglyceride (P˂0.05). Blood urea nitrogen significantly increased in hypercholesterolemia group in compare to control group (P˂0.05). After the administration of essential oil with a minimum and maximum dose in hypercholesterolemia rats, the level of urea in the blood significantly decreased (P˂0.05). The level of ALT and AST in hypercholesterolemia rats significantly increased in comparison with the control group (P˂0.05). AST level significantly reduced in the groups of rats which received minimal and maximal doses compared to the group hypercholesterolemia (P˂0.05). By lowering blood lipids, urea and liver enzymes after the use of essential oils, it seems that the Thymus daenensis dose-dependent is effective in improving liver function, kidney and high level of  lipid.
