Chemical Composition and Antifungal Activity of Essential Oils Isolated from Juniperus Oxycedrus L
The chemical composition of essential oils isolated from the leaves of Juniperus oxycedrus by hydrodistillation was analyzed by GC-MS. 42 compounds, representing 96.73% of total oil, were identified. J. oxycedrus oil was found to be rich in α-pinene (39.63%), manoyl oxide (12.34) and z-caryophyllene (4.1%) and characterized by relatively high amounts of monoterpenes hydrocarbons and sesquiterpe...
متن کاملIn Vitro Cytotoxicity of Two Subspecies of Juniperus excelsa on Cancer Cells
Objective(s) The cytotoxic effects of crude ethanol extracts of some previously tested Iranian conifers on tumor cell lines have motivated us to screen different parts of two subspecies in these genus. Materials and Methods Terminal branchlets and berries of Juniperus excelsa subsp. excelsa and J. excelsa subsp. polycarpos were collected, dried and extracted with ethanol/H2O (80/20 v/v) via pe...
متن کاملCryptic speciation between Juniperus deltoides and Juniperus oxycedrus (Cupressaceae) in the Mediterranean
Analyses of individuals classically treated as Juniperus oxycedrus L. var. oxycedrus from Morocco, Portugal, Spain, France, Italy, Greece and Turkey, using DNA sequencing of nrDNA (ITS 1, 5.8S, ITS 2) plus RAPDs, leaf terpenoids and morphology revealed that two cryptic, genetically distinct but morphologically almost identical species are present. These species, J. oxycedrus L. var. oxycedrus a...
متن کاملChemical composition and analyses of enantiomers of essential oil obtained by steam distillation of Juniperus oxycedrus L. growing in Algeria
Essential oil of Juniperus oxycedrus growing in Algeria was obtained by steam distillation extraction method. The oil was analysed by capillary columns (non-polar DB5 and HP-chiral-20B) using gas chromatography with flame ionization and mass spectrometric detections. The compounds were identified according to their retention indices and mass spectra (EI, 70 eV). The oil contained α-pinene (36.7...
متن کاملRadical-Scavenging Activity and Ferric Reducing Ability of Juniperus thurifera (L.), J. oxycedrus (L.), J. phoenicea (L.) and Tetraclinis articulata (L.)
Objective. The aim of this work is to study and compare the antioxidant properties and phenolic contents of aqueous leaf extracts of Juniperus thurifera, Juniperus oxycedrus, Juniperus Phoenicea, and Tetraclinis articulata from Morocco. Methods. Antioxidant activities of the extracts were evaluated by 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical-scavenging ability, Trolox equivalent antiox...
