Achillea millefolium L. is a well-known species amongst the members of Achillea (Asteraceae) which grows naturally in Iran. In this study, the natural habitats of Achillea millefolium L.were identified in different regions of East Azerbaijan province during the growth season in 2011. The evaluation of morphological variation in 35 genotypes of seven populations of Achillea millefolium L. was carried out to determine superior characters for future breeding programs and medicinal purposes. In this study, 14 quantitative and qualitative characters were evaluated. Flowering stems were used to investigate the quantity of essential oil. Data of locations, vegetative and reproductive characters of each population and the amount of essential oil obtained from each location were recorded. Results were analyzed using cluster analysis with SPSS software. Populations were clustered based on vegetative and reproductive characters and the amount of essential oil. The results of simple correlation analysis showed the existence of significant, positive and negative correlations among some important characters. Factor analysis was also used for defining the determinant factors. According to the factor analysis, flowering stem length, internode length and leaf width constituted the main factors. The populations of Achillea millefolium L. were separated into four groups by cluster analysis using Ward method. The most similar populations were Pirbala, Kondlaj and Jolfa, while Shabestar and Zonoz were separated from other populations. Also populations of Bonab and Basmenj were clustered as a separate group. In conclusion, in this study from all populations, Basmanj and Jolfa populations due to higher yield of essential oil as well as higher adaptability to region climatic conditions are recommended for further physiological and breeding studies.

The effect of methyl jasmonate (MeJa) upon Agastache foeniculum [Pursh] Kuntze was investigated in aspects of enzymatic activities of phenylalanine ammonialyase (PAL) and 4-coumarate:CoA ligase (4CL), total phenolic content and total protein. The experiments were carried out based on a completely randomized design under a hydroponic system. The plants were subjected to different concentrations of MeJa (0, 0.1 and 1 mM). The PAL activity significantly increased in plants treated with 1 mM MeJa for 24 h compared with 0.1mM MeJa and control. In addition, 4CL activity also significantly increased at 24 h after 1mM MeJa treatment compared with 0.1mM MeJa treatment and control. However, MeJa treatments did not have any significant effect on total phenolic compounds after 8, 12 or 24 h of treatment compared with controls of those times. Total protein content significantly increased with 1 or 0.1 mM MeJa treatments after 24h of treatment compared with control plants.

Castor bean (Ricinus communis L.) is one of the most important medicinal plants used in pharmaceutical, cosmetics and hygienic industries in many developed countries. Oil obtained from plant's seeds is of the most valuable aperients in medicine. The purpose of this research was determining the effects of climatic factors (seven different locations) on oil content and fatty acids composition of castor bean plant and increasing quantity and quality of oil. The results showed that climatic factors had significant effects on oil content and fatty acids composition and there were significant differences among the different climates (P<0.01). The highest oil content was reported from West of Tehran (52%) and Marand (51%) regions. Based on the results of fatty acid analysis by Gas Chromatography (GC), eight major fatty acids were observed in castor oil. Ricinoleic acid (18:1 Δ9c-12OH) was known as the major oil fatty acid in Castor bean. The highest Ricinoleic acid was reported from Urmia region (88.94 percent) and the lowest Ricinoleic acid was recorded from Shabestar region (85.72 percent). Other fatty acids identified from various regions including linoleic acid (2.25 to 4.73 percent), palmitic acid (0.9 to 2.13 percent), oleic acid (3.05 to 4.22 percent), stearic acid (0.55 to 1.54 percent), linolenic acid (1.35 to 2.88 percent), dihydroxystearic acid (0.51 to 0.85 percent) and eicosanoic acid (0.86 percent).

Lemon thyme (Thymus× citriodorus (Pers.) Schreb) is a perennial sub shrub medicinal plant belonging to the Lamiaceae (Labiatae) family. This plant is a hybrid between Thymus vulgaris and Thymus pulegioides. It has been used as a diaphoretic and for bronchitis. The oil has been found to possess antimicrobial and antifungal activity. This study aims to determine the best harvest time of Lemon Thyme (Thymus × citriodorus) for maximum herbal yield and quantity of essential oil. This research was done at the Botanical Garden of Zardband Company located in the northern Tehran, Iran. Aerial parts of 4-year-old plants were harvested from 10 centimeters of land at 4 stages including: before flowering, beginning of flowering, full flowering and fruit set in the beginning of June to the end of July and then were air dried in the shade. Harvest time had a significant effect on fresh and dry weight of aerial parts in 0.1% probability level. According to the results maximum amount of fresh and dry weight of aerial parts of T× citriodorus plant were obtained from full flowering and fruit set stages. Based on the results harvest time had no significant effect on the essential oil of T× citriodorus. Although the highest essential oil content (2.21%) was extracted at beginning of flowering stage but there was no significant difference among different phonological stages. In conclusion, more suitable time for harvesting of T×citriodorus to achieve the maximum yield of essential oil production is at fruit set stage.

Feverfew (Tanacetum parthenium L.) is a perennial herbaceous essential oil bearing plant belongs to Astraceae family. This plant is a valuable and important medicinal herb which has many therapeutic properties. Recent investigations have shown its excellent anti-migraine effects of it. Other properties of this plant are anti-inflammatory, analgesic, promote menstrual flow and reduce fever, antiseptic and anti-rheumatic effects. This investigation was conducted to study the antibacterial properties of feverfew essential oil, as well as determination of the content and composition of essential oil before doing antibacterial assessments. The aerial parts of Tanacetum parthenium were harvested in summer when the plants were in full blooming stage. The collected aerial parts were then dried in the shade. The essential oil of aerial parts was extracted by hydro-distillation technique using Clevenger apparatus and was analyzed by capillary GC and GC/MS method. Anti bacterial properties of the essential oil on four pathogenic bacteria were determined by using broth dilution and well diffusion agar methods. The essential oil showed the maximum anti bacterial effect on E. coli and the minimum on S. aureus and P. aeuroginosa. The essential oil content of aerial parts was 0.66% (w/w) based on dry weight. The amount of camphor which is the main constituent of the oil and as an antiseptic component was 48.9%. In conclusion the results of this study showed thatthe essential oil of feverfew is rich of camphor and is considerable as an anti-bacterial agent in drug and food industries.

This field experiment was conducted from April to October 2005 in order to study the effects of different nitrogen levels (0, 50, 100, 150 and 200 kg ha-1) on essential oil content and compositions of Mexican marigold (Tagetes minuta L.). The utilization of nitrogen significantly affected essential oil content and compositions of Mexican marigold compared to control samples without nitrogen fertilizer. The application of 200 kg ha-1 nitrogen gave the highest oil content (1.16%). The results of the oil analysis showed that the constituents of the oils varied between nitrogen levels. There fore it could be concluded that for maximum production of essential oil, Mexican marigold should be grown with 200 kg ha-1 nitrogen but in order to preserve environment by decrease consuming fertilizer and soil management it is better to suggest 150 kg ha-1 nitrogen to produce safer crops because of the little differences of 150 with 200 kg ha-1 nitrogen on oil content.
