It is a considerable plant for its high amount of essential oil. The aim of this study is comparing the essential oil of cultivated plant with its natural samples. The aerial parts of wild sample were collected from Jeirod of Tehran province and cultivated sample gathered from field in Research Institute of Forest and Rangelands. Essential oils isolated by hydro-distillation and analyzed by a combination of capillary GC and GC/MS. The results showed that there are some similarities in the cultivated and wild samples. In the oil of wild sample limonene (29.1%), methyl geranate (17.7%), geranial (15.8%) and neral (11.9%) were the major components. In the oil of cultivated sample myrthenol (30.1%), limonene(23.6%), geranial (14.3%) and neral (9.3%) were the main components.

The cuminaldehyde compound which possesses the highest percent of Cuminum cyminum L. oil, was affected significantly (at 0.01 level) by planting date. However, different levels of irrigation did not have significant effect on cuminaldehyde. The p-cymen compound was in the second rank in term of percentage rate in the oil of Cuminum cyminum. Different levels of irrigation had significant effect on the amount of p-cymene (at 0.05 level).

The essential oil of flowers and latex has distinctive odor and honey bees which are effective pollen carriers of this species, are mostly being attracted to its flowers. Therefore, the flowers oil of cultivar UC/100, collected in July 2004 from Research Institute of Forest and Rangelands field, was investigated. The essential oil isolated by hydro-distillation was analyzed by a combination of GC and GC/MS. The mean oil content was 0.8% (w/w). A total of sixteen components were identified representing 97.6% of the oil. The main constitutes of the essential oil were α-pinene (27.2%), b-phellandrene (17.0%), γ-eudesmol (11.3%), β-pinene (10.0%), β-eudesmol (9.0%), bicyclogermacrene (4.0%).  Other components present in appreciable amounts were sabinene (7.3%), α-eudesmol (1.9%), bornyl acetate (1.6%), germacrene D (1.4%) and (Ε)-β-ocimene (2.2%).

One of theses endemic species is N. heliotropifolia. In this research the essential oil of N. heliotropifolia was investigated in three different stage of plant growth. The aerial parts of N. heliotropifolia at before flowering, beginning of flowering and complete flowering were collected from Hamedan province. Essential oils isolated by hydro-distillation from the aerial parts of three samples, were analyzed by a combination of capillary GC and GC/MS. The yields of essential oils were obtained 0.75%, 0.63% and 0.4% (w/w) respectively. So the oil yield of N. heliotropifolia was decreased from before flowering stage to complete flowering stage.  Thirty-six components were identified in the oils. The main constituent of the essential oil at before flowering stage was limonene (40.1%), that decreased by plant growth. The second main component of the oil in this stage was b-pinene (11.1%), that increased to 23.3% in the beginning of flowering, then decreased in fool flowering. The other main compounds of the oils were 1,8-cineole, b-caryophyllene, (Z)- b-farnesene, g-mmurolene abd bicyclogermacrene.

The aerial parts of Thymus pubescens were collected at four various localities in the Tehran province: Lar valley and Damavand (East of Tehran province), Sirachal and Fasham (Northwest of Tehran province). Essential oils were isolated by steam distillation from the plant material at two stages, before flowering (BF) and at full flowering (FF). The yields arranged between 0.34% and 0.86% at BF stage and between 0.40% and 2.03% at FF stage. In most sites of collection the oil content at BF stage was less than FF stage and the oil percentage of plant material from Lar valley and Damavand was more than of Sirachal and Fasham.  At BF stage 25 compounds and at FF stage 26 compounds were characterized by means of GC and GC/MS. Major constituents were: carvacrol, thymol, g-terpinene, r-cymene, borneol, methy carvacrol, b-caryophyllene, 1,8-cineol + limonene and Geraniol. Twenty-three constituents were common at two stages. Geranyl acetate and thymyl acetate were found just at BF stage and geranial, nerol, and thymodihydroquinone were found just at FF stage.

Juniper as one of the most resistant tree species to extreme conditions, frost (up to –40°C) and drought, plays important role in mountainous regions of Iran. In this study, by investigation on qualitative and quantitative characteristics of essential oils of leaves and berries (female cones), the effects of environmental factors were studied on metabolism of secondary products. The volatitale constituents of the Leaves and berries of male, female and male-female trees isolated by steam-distillation were analyzed by GC-MS. Results indicated that the amount of essential oil in berries is higher than that in leaves. Seasonal alteration of essential oil of berries differs from leaves. The essential oil of berries increase during growth period, however decreased in leaves. Besides drying has increasing effect on essential oil. In total 32 terpenoidic components were  found that α-pinene, limonene, trans-verbenol, cis-verbenol, verbenone, Υ- elemone and elemol were the important ones. α-pinene up to 70% of essential oil content was the highest component. Seasonal alteration of each component was very variable. Drying effect can be valuable for isolation of components and commercial applications.

In present study we selected Mentha longifolia (L.) Hudson var. callianta, which cultivated in Research station of Alborz (Karadj). The volatile oil extracted from plant by steam distillation method and analyzed by GC and GC/MS. The major constituents obtained from var. callianta in flower oil were piperitone (70.22%), piperitenone (9%), 1,8-cineol (7.8%) and in leaf oil were piperitone (49.7%), 1,8-cineole (18.4%), piperitenone (15.8%).

Five irrigation treatments determined that consisted of (i) a control which was irrigated to full field capacity during the growing season (FC), (ii) two moderate water stress treatments during vegetative (LS1) and flowering stages (LS2) and (iii) severe water stress treatments during flowering stages (HS). The volatile constituents of the aerial parts of cultivated S. hortensis were isolated by steam distillation and analysed by GC/MS. Result showed that the oil acclimation under greater soil water stress increased significantly especially in severe treatment. This treatment at the flowering stage affected on the quantity of the essential oils more than the moderate stress in vegetative and flowering stages. The main oil constituents were carvacrol [44.5% (LS2), 42.6% (LS1)] and g-terpinene [40.9% (FC), 37.8% (HS)]. The amount of carvacrol increased under two moderate stresses but g- terpinene content decreased after moderate and severe stress.

The acrial parts of this fragrant plants were collecteed from National Botaanical Garden of Iran in julay 1998 at itss full flawering stage. The essential oil was extracted by steam distillation method and analysed by GC/MS B-caryophyllene (29.6%), B-pinene (15.9%) and cis-B-farnesene (11%) were the  major component in the essential oil.
