conclusions antioxidant activity of this essential oil could be somehow attributed to high contents of carvone, carvacrol and thymol. the volatile oil of this plant could have the potential of other biological activities, so further experimental investigations are recommended on this essential oil. results analyses of yellow colored essential oil yielded 88.22% of total oil with 67 components. ...
Listronotus maculicollis Kirby is a highly destructive pest of low mown, cool-season turfgrasses in the northeastern United States and Canada. Behavioral and electrophysiological assays were conducted to identify compounds thatmaybeuseful in developingnovelmonitoring techniques. In Y-tube assays, males and females responded differently to volatiles from intact and clipped annual bluegrass (Poa ...
Knowledge of the release of volatile organic compounds (VOCs) by cells provides important information on the origin of VOCs in exhaled breath. Muscle cells are particularly important, since their release of volatiles during the exertion of an effort contributes considerably to breath concentration profiles. Presently, the cultivation of human skeletal muscle cells is encountering a number of ob...
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...
We present a novel kinetic multi-layer model for gas-particle interactions in aerosols and clouds (KMGAP) that treats explicitly all steps of mass transport and chemical reaction of semi-volatile species partitioning between gas phase, particle surface and particle bulk. KMGAP is based on the PRA model framework (Pöschl-RudichAmmann, 2007), and it includes gas phase diffusion, reversible adsorp...
The heterogeneous processing of organic aerosols by trace oxidants has many implications to atmospheric chemistry and climate regulation. This review covers a model heterogeneous reaction system (HRS): the oleic acidozone HRS and other reaction systems featuring fatty acids, and their derivatives. The analysis of the commonly observed aldehyde and organic acid products of ozonolysis (azelaic ac...
BACKGROUND Although grape wines have firmly dominated the production and consumption markets of fruit wines, raspberry, strawberry, and mulberry have been utilized to make wines because of their joyful aroma and high contents of polyphenolic phytochemicals and essential fatty acids. However, little is known about aromatic compounds of the wines produced from these three fruits. METHODS The ar...
Background : Taraxacum Syriacum Boiss from Taraxacum Officinalis species is used in traditional herbal medicine for the treatment of jaundice, liver disorders and gallstones. This study was designed to investigate the ethanolic extract effect of the root of Taraxacum Syriacum (TSBE) on Acetaminophen-induced nephro-toxicity. Materials and Methods: The root of Taraxacum Syriacum Boiss were analy...
Peach (Prunus persica L.) is an economically important fruit crop worldwide due to its pleasant flavor. Volatile organic compounds (VOCs) are vital factors for assessing quality. Here, we constructed the VOC profiles top eight popular commercial peach cultivars produced in Shanghai by combining gas chromatography-mass spectrometry (GC-MS), odor activity value and chromatograph-ion mobility (GC-...
In order to reveal the flavor characteristics of Chinese pancakes, aroma and taste compounds seven traditional pancakes were identified. The results showed that electronic nose (E-nose) analysis with PCA could successfully distinguish profiles pancakes; principal components PC1 PC2 represented 75.74% 23.2% total variance (98.94%) respectively. Meanwhile, discrimination index based on tongue (E-...
