Essential oils of Satureja spp. contain valuable components, such as thymol and carvacrol. This research was carried due to evaluate essential oil quality and quantity of different accessions of Satureja species in cultivated condition., Seeds of 35 accessions of 10 Satureja species were collected from natural habitats and the seedlings were planted, using a randomized complete block design with for three replications at Medicinal Plants Research Station, Yazd, Iran. Aerial parts of plants were collected during four consecutive years, air dried in shadow and essential oils were extracted with hydrodistillation clevenger method. Essential oil compounds were identified by Gas chromatography (GC) and chromatography-mass spectroscopy (GC/MS). Analysis of variance showed significant differences at 1% between accessions for percentage of essential oil and essential oil yield per hectare. According to the results, accessions 15 (Satureja rechingeri) from Ilam province with 5.8% and 113.9 kg/ha essential oils, and 64% carvacrol and 12.2% thymol; accession 107 (S. spicigera) from Gillan province with 2.4% and 75.5 kg/ha essential oils, and 9.2% carvacrol and 43.4% thymol; accession 24 (S. rechingeri) from Ilam province with 4.2% and 63.8 kg/ha essential oils, and 75.4% carvacrol and 6.2% thymol; and SKM (S. bachtiarica ) from Yazd province with 2.6% and 51.5 kg/ha, essential oils, and 66% carvacrol and 0.5% thymol, respectively, showed the highest essential oil production in Yazd, Iran.

Thymuskotschyanus Boiss. & Hohen. is a perennial medicinal shrub growing wild in some regions of Iran including Yazd province. This research was carried out in order to analyze oil quantity and quality of cultivated Thymuskotschyanus in the Medicinal Plants Farm, Yazd, Iran. The seeds of 19 accessions collected from natural habitats were sown in a greenhouse and the seedlings were planted in the farm. Shoots were harvested at 50% flowering stage in the second year and dried under shadow. Essential oil was extracted with water distillation method and oil components were identified after determining oil content. The highest amounts of oil content respectively were related to accessions TK7 (3.42%), TK12 (3.22%), TK17 (2.66%) and the lowest amount was observed in accession TK6 (0.79%). The highest amounts of oil production respectively were recorded in accessions TK5 (38.3kg/ha), TK7 (36.4kg/ha) and TK12 (36.1 kg/ha) and the lowest amount was related to TK1 (1.3 kg/ha). Cluster analysis based on eleven oil components classified the accessions into three groups. The first group, (TK2, TK6, TK13, TK18, TK16, TK19), was rich for thymol-p-cymene, the scond group (TK1, TK3, TK4, TK5, TK7, TK11, TK14, TK15, TK17) for carvacrol-thymol and the 3rd group (TK8, TK9, TK10, TK12) was rich for Geraniol-linalool. In general, accessions TK7, with 3.42% oil content, 36.4 kg/ha oil production and 63.8% carvacrol; TK14, with 2.2% oil content 35.5 kg/ha oil production and 47.2% carvacrol and thymol, TK5 with 2.4% oil content, 38.3 kg/ha oil production and 57% thymol and carvacrol are proposed as superior accessions.

Savory (Satureja) consists of 17 herbaceous annual and perennial species in Iran and Satureja rechingeri Jamzad is one of the endemic species in this country. This research was carried to study oil quantity and quality in S. rechingeri. Seeds of eight accessions, collected from natural habitats, were sown in a greenhouse and the seedlings were planted in the Medicinal Plants Farm, Yazd, Iran. Essential oil was extracted from shadow dried flowering shoots with water distillation method and oil components were identified after determining oil content. Cluster analysis based on oil components classified the accessions into two groups, one of which was rich in carvacrol (SR1, SR2, SR3, SR5, SR7, SR8) and the other was rich in both carvacrol and thymol (SR6 and SR4). Based on the results of this study, SR4 with 5.85% essential oil, 113.9kg/ha oil yield, 64% carvacrol and 12.2% thymol , and SR6 with 4.22% essential oil, 63.8 8kg/ha oil yield, 75% carvacrol and 6.2% thymol are proposed as superior accessions.

Satureja belongs to lamiaceae with different species throughout the world. Annual and perennial species of this medicinal plant grow naturally in Iran, of which nine species are endemic. In this research, perennial species of Iranian savory were evaluated during 2009-2013, Yazd, Iran. Accessions of different species were cultivated at Research Station of Medicinal Plants using a randomized complete block design. Different traits including percentage of plant establishment, plant height, plant canopy diameter, shoot fresh yield, shoot dry yield and oil content were measured. Variance analysis showed significant differences (p<0.01) among accessions for plant establishment, plant canopy diameter, plant height, essential oil percentage, shoot dry yield and leaf dry yield . Based on mean comparisons, SKM (Satureja bachtiarica) from Yazd, 107 (S. spicigera) from Gilan, 15 (S. rechingeri) from Ilam, 123-1 and 123-2 (S. mutica) from Khorasan province were superior accessions for valuable agronomic traits such as percentage of establishment, shoot yield and oil content.
