“…4aα,7α,7aα-Nepetalactone, which was the main component of our oil, has been detected as the major one in four Nepeta species growing in Turkey [21] and also in N. cataria growing in Germany [22], while caryophyllene oxide, which was abundant in N. cataria from Lebanon [23] and Lithuania [24] (6.4%, 7.3% respectively), was not found in our work. β-Caryophyllene, which was the third major component of our oil, has been reported in the oil of some Nepeta species such as N. cataria [23], N. daenensis [25], and N. fissa from Iran [26], and in N. curviflora growing in Lebanon [23]. On the other hand, 1,8-cineole, which was the most abundant component in many Nepeta species [4, 27-30], was not present in our work.…”

The genus Nepeta (Lamiaceae) comprises 250 species of perennial herbs that are distributed in Europe, Asia, North Africa, and the mountains of tropical Africa. These plants are commonly known as catmint [1]. The common Persian name of this genus is pune-sa, and about 67 species are recorded in Iran [2]. Many Nepeta species have some biological activity and are used in folk medicine because of their antispasmodic, diuretic, antiseptic, antitussive, antiasthmatic, and febrifuge activities [3][4][5][6][7][8]. Nepeta cataria L. (Lamiaceae) is one of the endemic species of this genus in Iran. N. cataria, commonly known as catnip, is native to Asia Minor and Southeast Europe and grows to a height of 90 cm. It is used as a fortifier, a disinfectant, and a cure against cold [1,9]. Literature surveys reveal that most oils of Nepeta species such as N. cataria contain nepetalactones as the main component. Antibacterial, fungicidal, and antiviral activities have been attributed to nepetalactones [3, 6, 10]. According to our finding, there is no report on the chemical composition of the essential oil of N. cataria growing in central Iran, so the aim of the present research was to determine the chemical composition of N. cataria essential oil. The constituents of the volatile oil were analyzed by gas chromatography (GC) and gas chromatography-mass spectroscopy (GC-MS). The components of the oil of air-dried herbal parts of N. cataria are listed Table 1, including percentages and retention indices of the components. Constituents are listed in order of their elution from an HP-5MS column. As is shown, nine compounds were identified in the oil of N. cataria, making up 98.0% of the total oil. Among the constituents of the volatile oil, 4aα,7α,7aα-nepetalactone (87.1%), 4aα,7α,7aβ-nepetalactone (3.1%), β-caryophyllene (2.5%), and β-pinene (1.7%) were the major ones; the other constituents were present in relatively small amounts, representing only (3.6%) of the total oil. Nepetalactone isomers, which are the major constituens in our oil, were present in the essential oil of several Nepeta spp [11][12][13][14][15][16][17][18][19][20]. It was found that nepetalactones were responsible for the feline attractant properties of Nepeta species. 4aα,7α,7aα-Nepetalactone, which was the main component of our oil, has been detected as the major one in four Nepeta species growing in Turkey [21] and also in N. cataria growing in Germany [22], while caryophyllene oxide, which was abundant in N. cataria from Lebanon [23] and Lithuania [24] (6.4%, 7.3% respectively), was not found in our work. β-Caryophyllene, which was the third major component of our oil, has been reported in the oil of some Nepeta species such as N. cataria [23], N. daenensis [25], and N. fissa from Iran [26], and in N. curviflora growing in Lebanon [23]. On the other hand, 1,8-cineole, which was the most abundant component in many Nepeta species [4, 27-30], was not present in our work. Also, linalool and germacrene D have been identified in sizable amounts in other Nepeta spec...

“…According to our results, nepetalactone isomers were not detected in N. satureioides oil as they were in N. involucrate [2], N. ucranica ssp. Kopetdaghensis [3], N. makuensis [4], N. fissa [5], N. glomerulosa [6], N. macrosiphon [7], N. heliotropifolia [8], N. denudata [9], N. glomerulosa subsp. carmanica [10], and N. ispahanica [11].…”

UDC 547.913The essential oil of Nepeta satureioides Boiss. from Iran was isolated by hydrodistillation in yield of 0.06% (w/w). The chemical composition of the essential oil was analyzed by GC and GC-MS. Forty-five compounds accounting for 97.4% of the total oil were identified. The major components were linalool (23.8%), (Z,E)-farnesol (14.7%), linalyl acetate (11.1%), β-caryophyllene (6.6%), lavandulol acetate (6.6%), caryophyllene oxide (6.4%), and (Z)-β-farnesene (3.4%). Oxygenated terpenoids were the main group of compounds.

“…Germacrene-D was the main component of the essential oil of N. ucrainica, which can also be seen as the main component of the oil of N. spicata. 18 Spathulenol, one of the main components of the oil, can be seen as the major compound of the oil of N. macrosiphon. 24 Neither nepetalactone nor 1,8-cineol were the main components of the oil of N. spicata, 18 N. fissa,…”

“…13 These oils are characterized by the presence of nepetalactone isomers, which have a specific opioid receptor subtype agonist activity, 14,15 but in our literature review we found that nepetalactone diasteromers were not present in some species of Nepeta, which can make their properties different. [16][17][18] We report here on the composition of the essential oil of Nepeta ucrainica L. ssp. kopetdaghensis, which has not been reported previously.…”

Experimental Plant material and isolation procedureThe plant material was collected in June 2001 from Kopetdagh, Tandurch National Park in Khorassan province during flowering stage. A specimen (herbarium no. 892) has been deposited in the Herbarium of the Faculty of Pharmacy, the Medical Sciences University of Mashhad. The aerial parts were air dried at ambient temperature in the shade and hydro-distilled using a Clevenger-type apparatus for 5 h. The yield of the oil was 0.04% and the oil was yellow in color. It was dissolved in n-hexane (Merck), dried over anhydrous sodium sulfate and stored at 4-6°C. Identification of the oil componentsGC analysis was carried out using a Varian GC 3600 chromatograph with DB-5 column (30 m × 0.25 mm i.d.; 0.25 µm film thickness). Oven temperature was as follows: 60°C to 260°C at 3°C/min; injector temperature 250°C; detector temperature, 260°C; carrier gas, He (0.8 ml/min); split ratio 1:20. GC-MS analysis was carried out using a Hewlett-Packard 6890 operating at 70 eV ionization energy, equipped with a HP-5 capillary column (phenyl methyl siloxane, 30 m × 0.25 mm i.d.; 0.25 µm film thickness) with He as the carrier gas and split ratio 1:20. Retention indices were determined by using retention times of n-alkanes that were injected after the essential oil under the same chromatographic conditions. The retention indices for all the components were determined according to the Van Den Dool method using n-alkanes as standard. 19 The compounds were identified by comparison of retention indices (RRI, HP-5) with
