The essential oils isolated by hydrodistillation from the leaves of two Eucalyptus gillii Maiden and E. microcarpa Subsp. macrocarpa Hook were analysed by GC and GC/MS. The main components identified in E. gillii oil were 1, 8-cineole (79.5%), trans-pinocarveol (8%) and ?-pinene (2.7%), and in E. microcarpa were 1, 8-cineole (77.3%), ?-pinene (5.6%) and terpin-1-ol (5.1%). Oils with high conten...

Eight essential oils of Chinese medicinal herbs (Angelica sinensis, Curuma aeruginosa, Cyperus rotundus, Eucalyptus robusta, Illicium verum, Lindera aggregate, Ocimum basilicum, and Zanthoxylum bungeanum) were obtained by hydrodistillation and the essential oil of Eucalyptus robusta leaves was analyzed by gas chromatography-mass spectrometry (GC-MS). A total of 22 components of the essential oi...

Nepeta is one of the biggest geniuses of Lamiaceae family which N. pungens, N. binaludensis, N. isphanica, N. pogonosperma and N. bracteata has been used traditionally in Iran. Nepeta pogonesperma is one of the endemic Nepeta species in Alamut region (Qazvin Province ). So in this research the aerial parts of Nepeta pogonesperma in full flowering stage were collected from Kheshchal altitudes of...

1,8-Cineole (cineole) is a Eucalyptus leaf toxin that defends against predation by herbivores such as the brushtail possum (Trichosurus vulpecula). The aim of the current study was to characterize the pharmacokinetics of cineole in the possum to improve understanding about how possums can avoid cineole toxicity when eating a Eucalyptus diet. Nine male possums were trapped in the wild and acclim...

Staphylococcus aureus ATCC 25923, Escherichia coli ATCC 25922 and Salmonella enteritidis CMCC (B) 50041, were used in the antibacterial tests of Cinnamomum longepaniculatum leaf essential oil and its five chemical constituents. The effect of 1, 8-cineole on the ultrastructural structure of the bacteria (S. aureus and E. coli) was also investigated by transmission electron microscopy. The C. lon...

The present study was designed to determine the effects of the essential oil of Laurus nobilis L. (Lauraceae) and its three main components on α-glucosidase and reactive oxygen species scavenging activity. The chemical composition of the essential oil from Laurus nobilis L. leaves was analyzed by GC/GC-MS and resulted in the identification of 29 compounds, representing 99.18% of the total oil. ...

The chemical composition of the essential oils of flower at the pre-flowering, full-flowering and post-flowering stage of A. annua was analyzed by GC and GC/MS and sixty-two components were identified. The main compounds in the pre-flowering oil were β-myrcene (37.71%), 1, 8-cineole (16.11%) and camphor (14.97%). The full-flowering oil contained predominantly caryophyllene (19.4%), germacrene D...
