OBJECTIVE Eucalyptus (Fam. Myrtaceae) is a medicinal plant and various Eucalyptus species possess potent pharmacological actions against diabetes, hepatotoxicity, and inflammation. This study aims to investigate essential oil composition from leaves and flowers of E. microtheca and E. viminalis leaves growing in the Southeast of Iran. MATERIALS AND METHODS The aerial parts of these plants wer...

Detailed mechanisms have been developed which describe the complete degradation of αand β-pinene. Gas-aerosol absorptive partitioning has been incorporated for 280 oxygenated products, and the mechanism for α-pinene has been used to simulate the time development of ozone, secondary organic aerosol (SOA) and, where applicable, NOX for the conditions of EUPHORE experiments performed at part of th...

?-Pinene represents a member of the monoterpene class and is highly distributed in higher plants like conifers, Juniper ssp. Cannabis has been used to treat respiratory tract infections for centuries. Furthermore, it plays crucial role fragrance flavor industry. In vitro assays have shown an enantioselective profile (+)- (?)-?-pinene antibacterial insecticidal activity, respectively. Recent res...

background: the genus tanacetum (compositae) is represented by 26 species in the flora of iran, 12 of them are endemic. one report on the analysis of essential oil of tanacetum polycephalum boiss. species has been published. objective: aim of this study is to determine the chemical composition of the hydrodistilled oil of tanacetum pinnatum boiss. of iranian origin for the first time. methods: ...

We compared the effectiveness of a dry collection cup (with an insecticide killing strip) to a wet collection cup (containing antifreeze) for use with Lindgren multiple-funnel traps in catching several common species of bark and wood-boring beetles, and their associates in southern pine forests. All traps were baited with either the binary combination of ethanol and (-)-alpha-pinene or the quat...

The cardiovascular activity of essential oils has been reported. Some studies showed that the main chemical components of these oils contribute to their pharmacological activity. Therefore, the cardiovascular activity of four monoterpenes and one sesquiterpene was evaluated in the present work. In non-anaesthetized normotensive rats, (+)-alpha-pinene, (-)-beta-pinene, (+/-)-citronellol and (+/-...

Abstract The heat capacity of different mixtures terpenes (α-pinene, β-pinene, limonene oxide) and solvents (acetone, toluene, ethyl acetate) at atmospheric pressure (85.1 kPa atm in Medellin, Colombia) were measured using a microcalorimeter several terpene molar fractions from room temperature to value close the solvent boiling point. analyzed acetone + α-pinene 298.15 323.15 K, toluene oxide ...
