Evaluation of the essential oil of Foeniculum vulgare Mill (fennel) fruits extracted by three different extraction methods by GC/MS.
BACKGROUND Hydrodistillation (HD) and steam-distillation, or solvent extraction methods of essential oils have some disadvantages like thermal decomposition of extracts, its contamination with solvent or solvent residues and the pollution of residual vegetal material with solvent which can be also an environmental problem. Thus, new green techniques, such as supercritical fluid extraction and m...
متن کاملThe effect of organic and biological fertilizers on essential oil content of Foeniculum vulgare Mill. (Sweet Fennel)
In order to evaluate the effect of different biological and organic fertilizers on essential oil content of sweet fennel (Foeniculum vulgare Mill), an experiment was conducted at Research field of Faculty of Agriculture, Shahrood University of Technology in 2010. The experiment was conducted in a completely randomized block design with 11 treatments and three replications. The experimental trea...
متن کاملChemical composition, antibacterial activity and mechanism of action of essential oil from seeds of fennel (Foeniculum vulgare Mill.)
Fennel (Foeniculum vulgare Mill.) is widely cultivated and used as a culinary spice. In this work, the chemical composition of the essential oil obtained by hydrodistillation of fennel seeds was analyzed by gas chromatography-mass spectrometry (GCeMS), and 28 components were identified. Trans-anethole (68.53%) and estragole (10.42%) were found to be the major components. The antibacterial activ...
متن کاملCytotoxicity of the Essential Oil of Fennel (Foeniculum vulgare) from Tajikistan
The essential oil of fennel (Foeniculum vulgare) is rich in lipophilic secondary metabolites, which can easily cross cell membranes by free diffusion. Several constituents of the oil carry reactive carbonyl groups in their ring structures. Carbonyl groups can react with amino groups of amino acid residues in proteins or in nucleotides of DNA to form Schiff's bases. Fennel essential oil is rich ...
متن کاملPhytotoxicity and stimulatory impacts of nanosized and bulk titanium dioxide on fennel (Foeniculum vulgare Mill).
The objective of the this study was to compare concentrations of nanosized TiO2 at 0, 5, 20, 40, 60 and 80 mg L(-1) with bulk TiO2 for phytotoxic and stimulatory effects on fennel seed germination and early growth stage. After 14 d of seed incubation, germination percentage highly improved following exposure to 60 ppm nanosized TiO2. Similar positive effects occurred in terms of shoot dry weigh...
