A more simplified method of identification of the tertiary aminopropiophenones formed from various allylbenzene derivatives is reported. By use of combined gas-liquid chromatography and chemical ionization mass spectrometry, one is able to detect and verify the chemical structure of the tertiary aminopropiophenones of elemicin on nanogram quantities in the crude basic urine fraction. By use of ...

Seeds of nutmeg are used as spice, but they are also abused because of psychotropic effects described after ingestion of large doses. It was postulated that these effects could be attributable to metabolic formation of amphetamine derivatives from the main nutmeg ingredients elemicin (EL), myristicin (MY), and safrole (SA). In a case of a suspected nutmeg abuse, neither such amphetamine derivat...

This study was designed to find some potential natural products and/or constituents inhibiting proinflammatory cytokine generation in lung inflammation, since cytokines such as tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) are pivotal for provoking airway inflammation. In our preliminary screening procedure, the 70% ethanol extract of the leaves of Perilla frutescens (PFE) was found ...

The SPME (Solid Phase Microextraction) analysis of the scent H. hircinum showed presence elemicin in a relevant amount eugenol. sample adriaticum collected Abruzzo 4-amino-5-(4-morpholinylmethyl)-2-oxazolidinone, ?-ocimene, decyl decanoate, and 9-tricosene as main components. at Marsico Nuovo has an aroma where component was pentadecyl hexanoate, 9-tricosene, methyleugenol, tetradecane, pentade...

Isolation and characterization of leaf volatiles in Anemopsis californica (Nutt.) Hook. and Arn. (A. californica) was performed using steam distillation, solid-phase microextraction, and supercritical fluid extraction. Thirty-eight compounds were detected and identified by gas chromatography; elemicin was the major component of the leaf volatiles. While the composition of the leaf volatiles var...

This study focused on five different subspecies of Portuguese Daucus carota L., to identify the main compounds in essential oils umbels from each subspecies. The isolation was performed by hydrodistillation methods followed further composition analysis gas chromatography-mass spectrometry, ultimately demonstrating that had major compounds. concluded found subsp. maritimus were geranyl acetate, ...

Infusions and decoctions of Cymbopogon ambiguus have been used traditionally in Australia for the treatment of headache, chest infections and muscle cramps. The aim of the present study was to screen and identify bioactive compounds from C. ambiguus that could explain this plant's anti-headache activity. A dichloromethane extract of C. ambiguus was identified as having activity in adenosine-dip...

Parsley (Petroselium crispum L.) is commonly used for its flavor, desired nutritional contents, and other health benefits. However, since the profile of a recently introduced curly-leafed parsley cultivar in Egypt has not been studied, an experiment was conducted to compare three harvest dates terms weight, essential oil (EO) content yield, concentrations major components whole herb, leaf, stem...

Chemical composition of the essential oils extracted from the leaves, stems, flowers and seeds of  Heracleum rechingeri Manden. were analyzed by GC and GC/MS. Twenty-four components were characterized for the leaf oil with Octyl acetate(47.2%), Octanol(15.2%) and E-caryophyllen (5.7%) as the main constituents. 25 compounds were identified in the stem oil with Elemicin (65.3%), Octyl acetate (13...
