In our screening program for new agrochemicals from Chinese medicinal herbs and wild plants, Zanthoxylum schinifolium essential oils were found to possess strong insecticidal activity against the maize weevil Sitophilus zeamais. The essential oils of Z. schinifolium fruits and leaves were extracted via hydrodistillation and investigated by GC and GC-MS. Estragole (69.52%) was the major compound...

The chemical composition of the essential oil of Etlingera yunnanensis rhizomes and its contact and repellent activities against Tribolium castaneum (Herbst) and Liposcelis bostrychophila (Badonnel) were investigated. The essential oil obtained from E. yunnanensis rhizomes with hydrodistillation was performed by gas chromatography-flame ionization detection and gas chromatography-mass spectrome...

Fennel (foeniculun vulgare L.) is a vegetal species that presents bioactive monoterpenes. These compounds are lipophilic substances almost insoluble in water. The best conditions to extract these substances, employs organic solvents or heating process. With the aim developing new extractive methods which green chemical principles cam be applied, this work was performed. effect of use ultrasound...

abstract in order to evaluate the effects of different organic and biological fertilizers on quantity and quality of essential oil of fennel an experiment was conducted in a completely randomized block design with three replications. the experimental treatments were two organic (compost and vermicompost) and two biological (pseudomonas putida and azotobacter chroococcum ) fertilizers, their all...

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...

The aim of this research was to determine the chemical composition and nematicidal activity of essential oil of Agastache rugosa flowering aerial parts against the root knot nematode, Meloidogyne incognita, and to isolate and identify any nematicidal constituents from the essential oil. The essential oil of A. rugosa aerial parts was obtained by hydrodistillation and analyzed by GC-FID and GC-M...

Fennel fruits (Foeniculum vulgare Mill.) represent one of the plant-based natural spices. This study aims to improve fruit yield and essential oil (EO) quality by reducing undesirable component, estragole, under different fertilizer treatments. The fertilizers included chemical nitrogen, phosphorus, potassium (NPK), also organic additive, rabbit manure (RM). For bio-fertilization, plants were i...

Essential oils of the fruits of three organically grown cultivars of Egyptian fennel (Foeniculum vulgare var. azoricum, Foeniculum vulgare var. dulce and Foeniculum vulgare var. vulgare) were examined for their chemical constituents, antimicrobial and antioxidant activities. Gas chromatography/mass spectrometry analysis of the essential oils revealed the presence of 18 major monoterpenoids in a...

BACKGROUND Anethole and estragole are monoterpene position isomers and constituents of essential oils from aromatic plants and were used in this study with the aim of analyzing their anti-inflammatory activity. METHODS The anti-edematogenic effects of anethole and estragole were evaluated through plethysmometry in Swiss mice. RESULTS Anethole inhibited carrageenan-induced edema at doses of ...

Estragole (EG) is biosynthesized in herbs including anise, basil, bay, tarragon, fennel and marjoram, and is thought to be a useful biomass for the food and health industries. Moreover, the metabolites from estragole are useful intermediates in organic synthetic chemistry. However, estragole has been transformed only by chemical methods, and no biocatalysts have been reported. In this paper, we...
