The genus Anthemis L. is the second largest genus in the Compositae family, which consists of 39 annual and perennial species scattered throughout Iran. In this research, a species of Anthemis lorestanica Iranshahr was collected from two regions in Isfahan province, namely Makdin region (sample 1) and Badum Valley region (sample 2) in 2017.  The samples were identified in the herbarium of the Research Institute of Forests and Pastures in the Department of Botany. The essential oils were extracted from its flowers and leaves by water distillation method (Klenger method). Then the essential oil samples were measured and identified by gas chromatography (GC) and gas chromatography connected to mass spectrometer (GC/MS). The amount of essential oil in sample 1 was 0.12% for flower and 0.08% for leaf. Major compounds in the flower consisted of methyl decanoate (18.6%), α-cadinol (11.1%), and n-tricosan (9.1%). Major compounds in leaves were neryl acetate (13.4%), α-cadinol (12.9%), and dihydro eudesmol (8.5%). Essential oil contents of sample 2 were 0.2% for flower and 0.08% for leaf. The main flower compounds included spathulenol (68.8%), dehydro-aromadendrane (5.2%), and oplopanone (3%). The main compounds of the leaves were oplopanone (12.3%), 1-icocen (11.5%), and dihydro eudesmol (10.9%). Manuscript profile

The aim of this study was to investigate the effect of habitat on the quantity and quality of essential oil of Teucrium stocksianum Boiss. Accordingly, the branch of this species at the time of flowering (August 2017 and 2018) were collected from 4 regions of Hormozgan province (northern side of Tang Zagh mountain at 1100 meters of altitude; Abmah mountain at 850 meters of altitude; Tang Zagh mountain at 1400 m and Enveh mountain at 2000 m) . Essential oils were extracted by hydrodistillation method ( Clevenger apparatus) and were analyzed by using GC and GC/MS. The results showed that with decreasing altitude, the amount of essential oil reduced, so that the lowest and highest amounts of essential oil belonged to the samples of Abmah mountain at 850 m and Enveh mountain at 2000 m, respectively. Chemical analysis of T. stocksianum essential oils showed that the common compounds in the essential oils of this species were elmol (2.4 to 8.5%), caryophylene oxide (3.0 to 7.1%) and β-eudsmol (2.2 to 12.1%). Compounds such as α-pinene and myrcene, the most volatile compounds found in essential oils, were not observed in lower-altitude samples, which may be related to high air temperatures in plant geographical location. Also, significant amounts of compounds such as valerianol, polgon, limonene and epi-alpha-cadinol were observed in some samples, which shows the effect of the ecological and climatic conditions on the quality of plant essential oil.

Ferula gummosa (Barijeh) belongs to the Apiaceae family and is one of the most important pasture, medicinal and industrial plants, whose oleo-gum-resin (galbanum) has a commercial aspect. The essential oil and oleoresin of F. gummosa are widely used in the food, pharmaceutical and cosmetic industries. The aim of the present study is to investigate and compare the physicochemical properties of the essential oil obtained from the oleo-gum-resin of two F. gummosa populations from Isfahan and Fars habitats. For this purpose, the oleo-gum-resin of F. gummosa was collected from two areas in Kashan and Fars. The essential oil was then extracted from the fresh oleo-gum-resin by water and steam distillation. The essential oil was analyzed quantitatively and qualitatively using GC and GC/MS devices. The appearance, physical and chemical characteristics of the essential oil of two populations of F. gummosa, including relative density, refractive index, optical rotation, and phytochemicals of the essential oil were investigated and compared. Based on the results, the essential oil of F. gummosa is a transparent and colorless liquid with a turpentine odour and a distinct green note. The essential oil of two populations of Kashan and Fars has relative density of 0.874 and 0.869, refractive index of 1.4810 and 1.4795, and optical rotation of 11.35° and 23.52°, respectively. The results of comparing the average physicochemical characteristics of the essential oil obtained from the oleo-gum-resin of the two F. gummosa populations from Fars and Kashan indicate that there is no significant difference in the traits of relative density and refractive index, and on the other hand, there is a significant difference in the amount of optical rotation of the two essential oil samples. Based on the essential oil analysis, hydrocarbon monoterpenes including β-pinene (71% and 68.8%), δ-3-carne (9.4% and 5.2%), myrcene (3.9% and 2.4%), α-pinene (3.6% and 3.4%) and limonene (2.4% and 15.6%) were identified as the main compounds of essential oil in two F. gummosa populations from Kashan and Fars, respectively.
