Emissions of biogenic volatile organic compounds (VOCs) have important roles in ecophysiology and atmospheric chemistry at a wide range of spatial and temporal scales. Tropical regions are a major global source of VOC emissions and magnitude and chemical speciation of VOC emissions are highly plant-species specific. Therefore it is important to study emissions from dominant species in tropical ...

The essential oil of the herb medicinal plant known as “smoke tree” (Cotinus coggygria Scop.) from Eastern, Anatolia (Turkey) was analyzed by Gas Chromatography-Mass Spectrometry (GC/MS). Twenty ingredients were identified for flowers representing 100% total while eleven characterized in leaf comprising 99.96% extracted. As thymol (31.33%) and carvone (20.57%) main flower oil, major determined ...

Lindera glauca is a shrub or small tree mostly distributed in China, Japan and Korea. However, reports on the biological activities of fruit essential oil (LGFEO) are limited. The study its chemical composition, antioxidant cholinesterase inhibitory were performed, along with molecular docking six selected compounds. LGFEO was extracted by hydro distillation analyzed GC-MS GC-FID. Antioxidant e...

ferulago angulata subsp. carduchorum (boiss. & hausskn.) d.f. chamb is a perennial species of the family apiaceae and is locally used as a flavouring agent and for some medicinal properties. the essential oil of this plant if found to possess antibacterial and antifungal activities. the present study is aimed to determine constituents of essential oils from inflorescence of four f. angulata sub...

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...

23 Experiments were conducted in North and South America during 2012-2013 to 24 evaluate the use of lure combinations of sex pheromones (PH), host plant volatiles 25 (HPV), and food baits in traps to capture the oriental fruit moth, Grapholita molesta 26 (Busck) and codling moth, Cydia pomonella (L.) in pome and stone fruit orchards 27 treated with sex pheromones. The combination of the sex phe...

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...

The essential oil of Stachys lavandulifolia Vahl (Lamiaceae) was isolated by hydrodistillation of the aerial parts of the plant, with a yield of 0.25%. The chemical composition of volatile oil was analyzed by capillary GC and GC/ MS. The main components were germacrene-D (13.2%), ?-phellandrene (12.7%), ?-pinene (10.2%), myrcene (9.4%), ?-pinene (8.4%) and Z-?-ocimene (5.8%).

The exotic wood-boring pest, emerald ash borer (EAB), Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), has been threatening North American ash (Fraxinus spp.) resources, this being recognized since its first detection in Michigan, USA and Ontario, Canada in 2002. Ash trees are killed by larval feeding in the cambial region, which results in disruption of photosynthate and nutrient trans...

BACKGROUND Plant material from different organs of Pistacia terebinthus L., (Anacardiaceae) were collected in Kosovo with aim to analyze the chemical variability of the essential oils among native populations and to test them for potential antibacterial activity against Staphylococcus aureus. METHODS Essential oils obtained from leaves, pedicels, fruits and galls were analyzed by GC-FID and G...
