Biodegradation of 2-methylenebornane (2-MB) by Enterobacter cloaceae, which is one of the dehydration products of 2-methylisoborneol (2-MIB) led to 2-MIB, 2methylcamphene (2-MC) and an unidentifiable oxidation product, in addition to the previously reported camphor and lactonic compound. On the other hand, 2-MC, which is another dehydration product of 2-MIB was oxidatively degraded to fenchone ...

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...

Thirteen samples of authentic absinthe dating from the preban era (i.e., prior to 1915) were analyzed for parameters that were hypothesized as contributing to the toxicity of the spirit, including naturally occurring herbal essences (thujone, pinocamphone, fenchone), methanol, higher alcohols, copper, and antimony. The total thujone content of preban absinthe was found to range between 0.5 and ...

With use of a conditioning paradigm, the ability of six squirrel monkeys to distinguish between 10 pairs of enantiomers, i.e., odorants that are identical except for chirality, was investigated. As a group, the animals were only able to discriminate between the optical isomers of α-pinene, carvone, limonene, and fenchone, whereas they failed to distinguish between the (+) and (-) forms of β-cit...

The fruits of Foeniculum vulgare (Foeniculi Fructus) have been widely used in Chinese medicine as an antiemetic, ameliorating stomach ailments and as an analgesic. In order to establish its potential for antiallergic use, inhibitory actions of the fruiton 5-lipoxgenase (5-LOX) and β-hexosaminidase release were evaluated. The 70% ethanol extract of this plant material (FR) considerably inhibited...

fennel (foeniculum vulgare mill.) is an industrial medicinal plant with different pharmaceutical and food applications. in this study, the leaf essential oil composition of 12 iranian accessions of fennel collected from different geographical regions was assessed. the essential oil yield of fennel leaves ranged from 0.65% (varamin accession) to 2.03% (tabriz accession). trans-anethole, fenchone...

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...
