The chemical compositions of essential oils from the flower and aerial parts (i.e., leaf and branch) of Eurya japonica were determined and quantified using gas chromatography-mass spectrometry (GC-MS). A total of 87 and 50 compounds were detected in the oils from the flower and aerial parts, respectively. The main compounds of the flower oil were linalool (14.0%), (9Z)-tricosene (12.0%), and no...

Cytogenetic analyses, of pollen viability, nuclear DNA content and RAPD markers were employed to study three chemotypes of Lippia alba (Mill.) (Verbenaceae) in order to understand the genetic variation among them. Different ploidy levels and mixoploid individuals were observed. This work comprises the first report of different chromosome numbers (cytotypes) in L. alba. The chromosome numbers of...

TRPA1 is a ligand-activated cation channel found in the intestine and other tissues. Components of food that stimulate TRPA1 receptors (phytonutrients) include allyl isothiocyanate, cinnamaldehyde and linalool, but these may also act at other receptors. Cells lining the intestinal mucosa are immunoreactive for TRPA1 and Trpa1 mRNA occurs in mucosal extracts, suggesting that the TRPA1 receptor i...

Several naturally occurring essential oils including carvacrol, anethole, cinnamaldehyde, cinnamic acid, perillaldehyde, linalool, and p-cymene were evaluated for their effectiveness in reducing decay and increasing antioxidant levels and activities in 'Duke' blueberries ( Vaccinium corymbosum). Carvacrol, anethole, and perillaldehyde showed the capability to promote total anthocyanins and tota...

BACKGROUND Recent malaria vector control measures have considerably reduced indoor biting mosquito populations. However, reducing the outdoor biting populations remains a challenge because of the unavailability of appropriate lures to achieve this. This study sought to test the efficacy of plant-based synthetic odor baits in trapping outdoor populations of malaria vectors. METHODOLOGY AND PRI...

Dependence of monoterpenoid emission and fractional composition on stomatal conductance (G(V)) was studied in Mediterranean conifer Pinus pinea, which primarily emits limonene and trans-beta-ocimene but also large fractions of oxygenated monoterpenoids linalool and 1,8-cineole. Strong decreases in G(V) attributable to diurnal water stress were accompanied by a significant reduction in total mon...

the aim of our work was to compare cytotoxic and membrane-damaging effects of o. majorana l. essential oil and linalool on hep g2 and to investigate their possible protective (antioxidant) effects against h2o2 induced membrane damage. the oils were investigated by gc and gc-ms and antioxidant activity was evaluated by dpph and -carotene–linoleic acid assays. assessment of cell viability was ma...

Objective: To determine the extraction technique and content of linalool, as dominant compound, in black betel essential oil from East Kalimantan using a validated analytical method.
 Methods: Extraction was carried out steam distillation. Essential oils were assessed by observing colour solubility ethanol. Using an Agilent GC-MS with 5977B (GCMSD) detector, DB-5MS column, helium gas carri...

The chemical composition of the Hydrolate of Citrus aurantium L. (Rutaceae) flowers (neroli) grown in Iran, and two commercial hydrolates were analyzed by GC/MS. Thirty compounds (90.3%) were identified in the Hydrolate by the use of laboratory apparatus, thirty-eight compounds (83.4%) in the Hydrolate from the traditional method and fifteen compounds (98.3%) in the industrially produced sample...
