Dorema D. Don. genus belongs to the Umbelliferae family with important medicinal and aromatic species, containing more than 16 species worldwide, of which 6 species have been reported in Iran. In this research, the essential oil composition of vegetative and reproductive organs of Dorema ammoniacum D. Don. obtained from Shahsavaran, Kashan was investigated. This species is endemic to semi-arid regions of Iran and Afghanistan, growing naturally on rocky and alluvial lands. The stem, leaf, fruit and root of this species were collected in spring 2011 and dried in shade (at room temperature). The essential oil was extracted by simultaneous steam distillation and solvent extraction (SDE). The chemical composition of the essential oil was analyzed by using GC and GC-MS. According to the obtained results, 18, 13, 12 and 12 components were identified in the essential oil of dry stem and leaf; fresh stem and leaf; fruits, and roots respectively of which the major components were as follows: (E)-nerolidol (11.7%), E, E-farnezyl acetone (8.9%), phytol (8.9%), di-n-butyl phthalate (6.9%), 2(E)-tridecen-1-al (6.1%) and α-farnesol( 5.5%) in the essential oil of dry stem and leaf; phytol (15.2%), (E)-nerolidol (14.6%), α-farnesol (14%), 2-(E)-tridecenol (12.8%) and tetradecanal (5.6%) in the essential oil of fresh stem and leaf; α-farnesol (41.2%), β-bisabolene (13%), α-bisabolol (6.4%), and (Z)-farnesal (5.5%) in the essential oil of fruits, and β-bisabolene (56.1%), elemicin (12.2%) and tridecanol (6.1%), in the essential oil of roots. Sesquiterpenes constituted the main chemical group in the essential oil obtained from the roots and fruts of Dorema ammoniacum in Shahsavaran, Kashan.

Melia L. genus, belonging to the Meliaceae family, has important tree species.There are more than 15 species of this genus in the world and two species from Iran have been reported so far. In this study, the chemical compositions of the essential oils of reproductive organs of M. azedarach L., cultivated in Kashan Botanical Garden, were investigated. The flowering branches and ripe fruits of this species were collected in the spring of 2009 and dried in the shade (at room temperature). The essentila oil was extracted by simultaneous steam distillation extraction method. The oil analysis was performed by using GC and GC-MS. The essential oil yield of flowering branches and fruits was calculated to be 0.02% and 0.01% (w/w), respectively.Ten and 35 chemical compositions were identified in the essentila oils of flowering branches and fruits of this species. The main components of the essential oils of flowers were E-nerolidole (39%), bicyclogermacrene (8.2%) and viridiflorol (8.1%). The main components of the essential oils of fruits were aromadendrene (21.9%), bicyclogermacrene (13.7%), globulol (8.1%), spathulenol (6.5%), allo-aromadendrene (4.7%), β-caryophyllene (4.7%). Oxygenated sesquiterpens were identified as main component in the essential oil of flowers, while the major chemical component of the essential oils of fruits were associated with hydrocarbon sesquiterpens, and hydrocarbon monoterpenes were not found in plant reproductive organs.

Haplophyllum A. Juss. is one of the most important genus of Rutaceae family, in which over 20 species have been reported for Iran. The purpose of this study was to extract and determine essential oil composition of three Haplophyllum A. Juss. species from Kashan. Leaves of the three species i.e. H. robustum Bge., H. glaberrimum Bge. & Boiss. and H. perforatum (M. B.) Kar. & Kir. were collected from deserts and mountainous areas around Kashan. Essential oil was obtained by hydrodistillation using an all-glass Clevenger-type apparatus. The analysis of the oils was performed by using GC and GC-MS methods. The essential oil yield of H. robustum was 1.02% (v/w) and 14 components were identified. Major components of the oil were 1,8-cineol (25%), β-pinene (12.2%) and sabinene (9%). The essential oil yield of H. glaberrimum was 0/08 % (v/w) and 13 components were identified, in which the major components were myrcene (42.9%), elemole (10.6%) and β-caryophyllene (8.9%). The essential oil yield of H. perforatum was 0.38 % (v/w) and 12 components were identified, in which the major components were elemole (37.6%), β-caryophyllene (%21.1) and α-pinene (19.1%). The major components of the essential oil in H. robustum and H. glaberrimum were monoterpens, but the essential oil of H. perforatum was rich of sesquiterpenes.

Nepeta L. genus belongs to Labiatae family that has important medicinal and aromatic species. More than 250 species in world and 67 annual and pernnial species in Iran have been reported. In this investigation, essential oil composition of Nepeta gloeocephala Rech. f., Nepeta sessilifolia Bunge and Nepeta laxiflora Benth have been staudied. The species are endemic to Iran and have natural habitats in Dorien, Ghohroud and Mashhad-e-ardahal of Kashan. The flowering branches of these species were collected in spring and summer and dried in shade (at room temperature). The flowering branches of the species subjected to volatile fraction were isolated by hydrodistillation using a Clevenger-type apparatus for 3 or 4 hours. After decanting and drying of the oils over anhydrous sodium sulfate, they were stored in vial at low temperature (4ºC) before analysis. The analysis of the oils was performed using GC and GC-MS. The results showed that, the essential oil of Nepeta gloeocephala Rech. f. was yellow in 1/3% (v/w) yield and 29 components were identified, among them, 1,8-Cineole (35.2%), Beta-pinene (21.8%), sabinene (7.8%), (E)-beta ocimen (7.1%), alpha-pinene (7.1%) and (Z)-ocimene (6.9%) were the major compounds. The essential oil of Nepeta sessilifolia Bunge was bright yellow in 0.65% (v/w) yield and 33 components were characterized, among them, spathulenol (25.8%), lavandulyl acetate (16.7%), limonene (6.4%) and geranyl acetate (4.17%) were identified. The essential oil of Nepeta laxiflora Benth was sharp yellow in 0.175% (v/w) yield and 30 components were identified, among them, alpha-pinene (19.7%), 1,8-cineole (11.8%), alpha-bisabolol (6.9%), delta-cadinene (6.8%), germacreneD-4-ol (6.2%), and caryophyllene oxide (4.4%) were main compounds.
