The essential oils isolated from different parts (flower, leaf, stem and root) of Nepeta Sintenisii Bornm. (family: Lamiaceae) growing in Khalkhal, Northwest Iran, were analyzed by GC and GC-MS. The oil yields were: flower 1.2 %, leaf 0.25 %, stem 0.06 %, and root 0.05 % (v/w). Fourteen compounds representing 98.7 % of the flower oil of Nepeta Sintenisii, were identified; among them 4aβ, 7α, 7aβ-nepetalactone (60.3 %), germacrene D (12.7 %) and 1, 8-cineol (8.2 %) were the major ones. Twenty constituents (95.7 % of the leaf oil) were identified of which 4aβ, 7α, 7aβnepetalactone (34.6 %), germacrene D (14.1 %), 1, 8-cineol (7.9 %), α-cadinol (6.8 %) and δ-cadinene (5.8 %) were the main components. The stem oil of the plant was characterized by higher amount of 4aβ, 7α, 7aβ-nepetalactone (64.2 %), α-cadinol (8.9%), α-pinene(6.7%), 4aα, 7áα, 7aβ-nepetalactone (5.2 %) and 1,8-cineol (3.6 %), among the eight components comprising 96.3 % of the total oil detected. Twelve compounds in root of plant were characterized representing 98.6 % of the components detected with 4aβ,7α,7aβ-nepetalactone (61.2 %), germacrene D (12.0 %),4aα,7α,7aβnepetalactone (8.5 %), 1,8-cineol (5.7 %) and β-caryophyllene(4.5 %) as the main constituents. The oil of flower, stem and root consisted mainly of monoterpenes, but monoterpenes and sesquiterpenes of leaf oil was approximately equal amount in the percentage (48.2 % and 47.5 % respectively).
Essential oil analysis of eight 'Nepeta' taxa in Iran
Mediterranean Botany, 2020
Nepeta is one of the largest and important genera of Lamiaceae that is found in many parts of the world as wild plants. These aromatic plants produce essential oil for various pharmaceutical and industrial products. The essential oil composition in eight taxa of Nepeta was analyzed. One natural population from each taxon was selected, and their essential oils extracted using Clevenger apparatus. Moreover, GC and GC/MS analysis methods allowed to reveal the variability in essential oil composition and profile among the studied taxa. The oxygenated monoterpenes were dominant in the oils of N. meyeri, N. mirzayanii, N. racemosa, N. binaludensis, and N. glomerulosa. Phytol was the major compound in the essential oil of N. kotschyi var. persica and N. saccharata (11.56% and 27.04%, respectively). 4aα,7α,7aβ-nepetalactone (73.89%) and 4aα,7β,7aα-nepetalactone (83.92%) were the major constituents in essential oil of N. mirzayanii and N. meyeri, respectively. 1,8-cineol was the principal co...

The volatile components of Nepeta gloeocephala Rech. f. (Lamiaceae) grown in Iran obtained by hydrodistilla-tion of aerial parts was analyzed by GC and GC/MS. Twenty-nine compounds, constituting 99.98% of the oil, were characterized. Among them 1,8-cineole (35.2%), β-pinene (21.8%), sabinene (7.8%), (E)-β-ocimene (7.1%), α-pinene (7.1%) and (Z)-β-ocimene (6.9%) were the major components of the oil, which was obtained in 1.3% yield.

Essential oils (EOs) because of being natural compounds and having antibacterial properties are important for health. The chemical composition of EOs might be affected by environmental conditions and plant growth and development stages. In this study, the essential oils and chemical compositions of aerial parts of Nepeta kotschyi Boiss. (Lamiaceae) were analyzed by gas chromatography (GC) and gas chromatography-mass spectrometry (GC/MS) at different plant phenological (in mid vegetative, 50% of flowering and fruiting) stages. The results showed that the EOs of Nepeta was affected by plant growth and development stages. So, both of content and their constituents were different in the plant phenological stages. The average percentage of EOs was ranged from 2.48 (in vegetative), 0.8 (in 50% of flowering), and 0.82 (in fruiting) stages. According to the results, 21 compounds with the range of 0.84-13.04 % in vegetative, 3 compounds with the range of 10.93-53.25% in 50% of flowering and 6 compounds with the range of 8.51-45.22% in fruiting stages were identified. The compounds 1,6,10-Nerolidol in vegetative (13.04%), Spathulenol in 50% of flowering (53.25%) and Caryophyllene oxide in fruiting stages (45.22%) had the highest value. Based on the results, the highest percentage of essential oils and compounds were related to the vegetative stage. The present study is the first report of the essential oil content of Nepeta during different plant phenological stages. The results of this study can be useful to understand the proper harvest time in Nepeta.

Talebi SM, Nohooji MG,Yarmohammadi M. 2017. Short Communication: Infraspecific variations in essential oil compositions of Nepeta fissa from Iran. Nusantara Bioscience 9: 318-321. Nepeta fissa C.A. Mey. is a member of Mint family (Lamiaceae) and distributed naturally in different regions of Iran. The aim of this investigation was to provide more information about the influence of environmental conditions on the essential oil composition of two populations, Polor and Dizin, of this species. The dry plant samples were submitted to hydrodistillation for 2.5 h, using a Clevenger-type apparatus. The highest amount of essential oil yields (0.2%) were obtained for Dizin population. Forty-nine compounds, representing 85.9 to 97.80% of the total essential oils, were separated and identified. In Dizin and Polor populations, the essential oils were characterized by the very high percentage of oxygenated monoterpenes (79.1%), oxygenated diterpenes (20.01%) that constituted the predominant class...
Study on essential oil of Mentha aquatica L. from Vietnam
American Journal of Essential Oils and Natural Products, 2015
The characterization of essential oils of Mentha aquatica L grown in two Provinces of Vietnam was performed by means of gas chromatography-flame ionization detector (GC-FID) and gas chromatography-mass spectrometry (GC-MS) techniques. The major constituents of the essential oils were epi-bicyclosesquiphellandrene (58.9% and 52.4% respectively) and limonene (21.1% and 31.4% respectively) for Thanh Hóa and Nghệ an Provinces, Vietnam. This compositional pattern may represent a new chemotype of the essential oils of M. aquatica.
Diversity in chemical composition and yield of essential oil from two Mentha species
The genus Mentha, which belongs to the mint family (Lamiaceae). Essential oil yield and chemical components of two Mentha species including Mentha longifolia (L.) Huds. and (Mentha spicata L.) collected from three ecotypes in Iran were investigated. The essential oils of samples were obtained by hydro-distillation, and analyzed using gas chromatography-mass spectrometry (GC-MS). A significant difference (p < 0.05) in oil yields was obtained from the aerial parts of two Mentha species. The essential oil yields were obtained from the aerial of M. longifolia, 0.62, 0.85 and 1.24 ml / 100 g dry matter identified in Ardestan, Saman and Kuhrang province, respectively and the aerial of M. spicata, 0.49, 1.02 and 1.54 ml / 100 g dry matter identified in Ardestan, Saman and Kuhrang province, respectively. Results indicated significant differences (p < 0.01) among the aerial for the main constituents in the essential oil from two Mentha species. The major constituents of the essential oil from the aerial of M. longifolia collected from Ardestan province were pulegone (31.21%), 1,8-cineole (23.01%), sabinene (6.76%), the aerial of M. longifolia collected from Saman province were pulegone (31.06%), 1,8-cineole (24.34%), sabinene (7.45%) and the aerial of M. longifolia collected from Kuhrang province were pulegone (36.42%) and 1,8-cineole (29.49%). The major constituents of the essential oil from the aerial of M. spicata collected from Ardestan province were 1,8-cineole (35.28%), carvone (30.71%), the aerial of M. spicata collected from Saman province were carvone (35.37%), 1,8-cineole (24.35%), pulegone (18.67%) and the aerial of M. spicata collected from Kuhrang province were
