Phytochemical and pharmacological properties of essential oils from Cedrus species
2017
Natural products frequently exert pharmacological activities. The present review gives an overview of the ethnobotany, phytochemistry and pharmacology of the Cedrus genus, e.g. cytotoxic, spasmolytic immunomodulatory, antiallergic, anti-inflammatory and analgesic activities. Cancer patients frequently seek remedies from traditional medicinal plants that are believed to exert less side effects than conventional therapy with synthetic drugs. A long-lasting goal of anti-cancer and anti-microbial therapy research is to find compounds with reduced side effects compared to currently approved drugs. In this respect, Cedrus species might be of interest. The essential oil isolated from Cedrus libani…
Phytochemical Analysis and Cytotoxicity Towards Multidrug-Resistant Leukemia Cells of Essential Oils Derived from Lebanese Medicinal Plants
2012
Juniperus excelsa fruit essential oil as well as J. oxycedrus, Cedrus libani, and Pinus pinea wood essential oils have been obtained with yields between 2.2 ± 0.3 % to 3.4 ± 0.5 % and analyzed by gas chromatography. Sesquiterpenes mainly characterized C. libani and J. oxycedrus essential oils, while in P. pinea and J. excelsa, monoterpenes were the most abundant compounds. In J. oxycedrus, cis-calamenene (7.8 %), cuparene (3.8 %), and cis-thujopsenal (2.0 %) have been detected for the first time. The cytotoxic activity of these essential oils against drug-sensitive CCRF-CEM and multidrug-resistant P-glycoprotein-expressing CEM/ADR5000 leukemia cells has been investigated (IC₅₀ values: 29.46…
Primi reperti in Sicilia su diffusione e biologia di Leptoglossus occidentalis Heidemann (Hetroptera: Coreidae), cimice americana dei semi delle coni…
2009
In this paper the first data on the distribution and biology of L. occidentalis in Sicily are reported; this bug, belonging to the family Coreidae, originates from North America, where it is regarded as a serious pest of conifer seed orchards. The first Sicilian specimens of L. occidentalis were found in September 2002 near Gangi (PA), while the first collecting data published until now refer to November 2003 in Niscemi (CL). The coreid is distributed in all Sicily provinces (30 collecting sites), from the sea level to 1.430 m a.s.l. on the mountains; it was collected on cones and plants of Pinus halepensis Miller, P. laricio Poiret, P. pinea L., P. nigra J.F.Arnold and Pseudotsuga menziesi…
