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...

Juniperus and Cupressus genera are mainly used as diuretic, stimulant, and antiseptic, for common cold and wound healing in Turkish folk medicine. In the present study, essential oils obtained from cones of Cupressus and berries of Juniperus were evaluated for their wound healing and anti-inflammatory effects. In vivo wound healing activity was evaluated by linear incision and circular excision...

Periplaneta americana (Blattodea:Blattidae) toxicity of 17 different plant-based essential oil against, adults were investigated. Used oils Lavendula angustifola (Lamiaceae), Zingiber officinale (Zingiberaceae), Citrus bergamia (Rutaceae), Juniperus virginiana (Cupressaceae), Piper nigrum (Piperaceae), Curcuna longa Betula lenta (Betulaceae), Myristica fragranaceae (Myristica fragranaceae), com...

Responses of American arborvitae (Thuja occidentalis), common yew (Taxus x media) and juniper (Juniperus communis) to enhanced UV-B irradiance were studied. Control plants were grown without UV treatment, but at identical PhaR and temperature regimes. Visual symptoms of the ultraviolet effect noted on Thuja shoots as brown/red discolouration were correlated with the accumulation of phenolic com...

Juniperus communis (Cuppraseae), a coniferous plant widely used as traditional medicine was evaluated for the antidiabetic and antihyperlipidemic activity on Streptozotocin(STZ)-nicotinamide induced diabetic rats. The methanolic extract of Juniperus communis (MEJC) (100mg/kg, 200mg/kg, b.w) was administered orally in diabetic group except the standard group (Glibenclamide 10mg/kg, b.w) and the ...

The essential oils of branchlets and fruits of Juniperus excelsa subsp. excelsa and Juniperus excelsa subsp. polycarpos were examined for their antioxidant activity. The compositions of the essential oils were studied by GC and GC-MS. To evaluation the antioxidants activity of the volatile oils, pure components and positive controls at different concentrations, thin-layer chromatography (TLC) s...

The impact of the size and shape of a selected group of herbs (dried juniper berries – Juniperus communis, dry blueberries – Vaccinium myrtillus, petals of cornflower – Centaurea cyanus) on the value of the volatility coefficient, the coefficient of sphericity and the critical speed was analysed in the presented research. A laboratory anemometer to measure the speed of air was used. The determi...

Umbelliferone, 13 lignans and an unusual compound 2-(3,4-methylenedioxyphenyl)propane-1,3-diol, were isolated from the leaves of Juniperus chinensis. The lignans include meso-secoisolariciresinol, 3,4-methylenedioxy-3’,4’dimethoxylignan-9’,9-olide, hibalactone, isohibalactone, 7-oxohinokinin, 7-hydroxyhinokinin, 7-acetyloxyhinokinin, (+ )-xanthoxylol, dihydrodehydrodiconiferyl alcohol, 3-methox...
