The essential oil of Leucas inflata Balf.f. (Lamiaceae), collected in Yemen, was analyzed using gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS) techniques. Forty-three components were recognized, representing 89.2% of the total oil. The L. inflata volatile oil was found to contain a high percentage of aliphatic acids (51.1%). Hexadecanoic acid (32.8%) and n-dodecanoic a...
The chemical composition of the essential oils of twenty-five populations of Cistus creticus subsp. creticus L. from the island of Crete (Greece) and their interpopulation variability were analysed in detail by GC-MS. 142 compounds were identified representing an average of 56.8-89.8% of the oil composition. The components are represented here by homologous series of monoterpenes, oxygenated mo...
Dendranthema indicum var. aromaticum, which is an aromatic plant with a strong and special fragrance throughout the whole plant, is used for the treatment of colds and headaches, and as a mosquito repellant in Shennongjia, Hubei province, China. To analyze the composition of the essential oil from this medicinal herb, we developed a gas chromatography-mass Spectrometry (GC-MS) method including ...
In this study, the chemical composition of the essential oils (EOs) extracted from aerial parts of native populations of Origanum vulgare ssp. vulgare from Iran was compared by GC and GC/MS. Plants were collected at bloom stage from their natural habitats located in Kaleybar, Sabalan, Meshkin Shahr and Chalus regions, respectively from East Azerbaijan, Ardabil, Ardabil and Mazandaran provinces....
The composition of the essential oil from leaves of Skimmia laureola was determined by GC and GC-MS. Twenty-eight components were identified, accounting for 93.9% of the total oil. The oil is mainly composed of monoterpenes (93.5%), of which monoterpene hydrocarbons and oxygenated monoterpenes represent 11.0% and 82.5%, respectively. Sesquiterpenes constitute only 0.3% of the total oil. Linalyl...

Objective(s):Various species of genus Trigonella are important from medical and culinary points of view. The essential oil of Trigonella torbatejamensis Ranjbar as an endemic plant in Iran has not been studied previously. The essential oil of this plant was analyzed by different methods for identification of its components. Materials and Methods: The essential oil composition of aerial parts o...
Bergamot essential oil (BEO) is the result of mechanical manipulation (cold pressing) exocarp (flavedo) hesperidium Citruslimon (L.) Osbeck Group (synonym Citrus × bergamia Risso & Poit.), resulting in bursting cavities embedded flavedo and release their contents. It chemically dominated by monoterpene hydrocarbons (i.e., limonene), but with significant percentages oxygenated monoterpenes l...
