Achillea vermicularis Trin., belonging to Astraceae family, is distributed at North and North-West Iran. It is used for treatment of arthritis infusion of the leaves, gastritis, asthma, and diseases of the liver in traditional medicine. In this study, for the first time, the seeds of A. vermicularis was collected from West Azarbayjan and cultivated in the field of Alborz research station, Karaj, Iran. In order to comparing the essential oil content and composition, flowering shoots and individual plant parts (flowers, leaves and stems) were collected in full flowering stage. The plant materials were dried at shade and their essential oils were obtained by hydro-distillation. The oils were analyzed by gas chromatography (GC) and gas chromatography/mass spectrometry (GC/Mass). The highest oil yields (w/w of dry weight) were obtained from flowers (0.53%) and leaves (0.52%) and the lowest oil yield was obtained from stems (0.24%). The oil yield of total aerial parts was 0.43%. According to these results, the distillation of all aerial parts is more suitable in comparison with oil extraction from the flowers that is common for other Achillea species, resulting in wasting a lot of essential oils in the leaves and stems. Twenty-nine compounds were identified in the essential oils, of which 1,8-cineol, camphor and piperitone were found in all essential oils in significant quantities. The content of camphor varied from 4.1% in stem oil to 19.2% in flower oil. Minimum and maximum content of 1,8-cineol was found in the stem oil (3.3%) and flower oil (23.3%), respectively. The minimum content of piperitone (4.9%) was obtained in stem oil and aerial parts oil was rich in piperitone (26.4%). There were special differences among the essential oils of plant parts. The presence of special compounds such as heptadecane (31.1%) and hexadecanol (18.6%) and n-henei cosine (4.5%) and n-octadecane only in stem oil (3.1%), germacrene D in aerial parts oil (13.6%), were other differences.

Achillea L. is one of the most important native medicinal genuses of Iran. Morphological and agronomic traits in 27 populations of A. millefolium and in 14 populations of A. bieberestini were studied using a random complete blocks design with three replications in Alborz Research Center, Karaj, Iran. ANOVA suggested significant differences among 27 populations of A. millefolium for all morphological and agronomic traits except full flowering time. Significant differences were found among 14 populations of A. bieberestini for all morphological and agronomic traits. In both species of A. millefolium and A. bieberestini significant correlation coefficient were found between the plant height and the flower diameter. Comparison of dry matter yield and other characteristics of different populations indicated that populations with dry and hot origin in both species of A. millefoliuum and A. bieberestini had better productivity. Population Semnan (21657) in A. millefoliuum and population Park golestan in A. bieberestini showed better characteristics in plant height, plant diameter, main inflorescence diameter, dry matter yield and inflorescence number as compared with other populations, which could be suggested for breeding programs.
