[1] The ozonolyses of six monoterpenes (a-pinene, b-pinene, 3-carene, terpinolene, a-terpinene, and myrcene), two sesquiterpenes (a-humulene and b-caryophyllene), and two oxygenated terpenes (methyl chavicol and linalool) were conducted individually in Teflon chambers to examine the gas-phase oxidation product and secondary organic aerosol (SOA) yields from these reactions. Particle size distri...

(in a chimney plume of an near-source oil palm processing plant) (MacKenzie et al., 2011). The aerosol loadings in the experiments performed here start well below these levels, and then increase through each run to reach levels considerably higher than the loadings in northern Borneo. Thus, it is likely that we observe more higher volatility species in the aerosol phase than we would at atmosph...

In this study, the variability of essential oil composition in different parts of summer savory was investigated. Extraction of essential oils from air-dried leaves and healthy seeds was done using water-distillation in Clevenger-type apparatus for 4 h. In total, 23 and 24 components were identified in the leaves and seeds of summer savory, respectively. Carvacrol (46.023%), Estragole (Methyl C...

The potential of three arbuscular mycorrhizal fungi (AMF) - Glomus mosseae, G. fasciculatum and G. intraradices- to enhance the production of essential oil and plant growth parameter was investigated in sweet basil (Ocimum basilicum). The AMF inoculation significantly increased plant height, fresh and dry matter yield, oil content and oil yield as compared to non-inoculated basil plants. Essent...

Phenylalanine amonia-lyase (PAL) is one of the most important enzymes that plays a key role in regulationof phenylpropanoid production in plants. It catalyzes the first step of the phenylpropanoid pathway in whichL-phenylalanine is deaminated to trans-cinnamic acid. This step is significant for metabolic engineering andhyper-expression of the major phenylpropanoid, methyl chav...

phytochemicals are good sources of natural antioxidants and have beneficial effects on human health. many of phenolic phytochemicals have shown antimicrobial and antifungal activity. anise hyssop ( agastache foeniculum [pursh] kuntze ) is a perennial aromatic plant of the lamiaceae family with antimicrobial and antifungal properties and useful for gastrointestinal problems. in this investigatio...

background food born pathogenic bacteria are the most important agents of infections in humans, and food spoilage also results in economic losses in food industry. objectives the aim of this study was the evaluation of chemical components, total phenolic content, antioxidant and antibacterial activities of artemisia dracunculus essential oil. materials and methods the essential oil of tarragon ...

background: basil (ocimum basilicum l.), a member of the lamiaceae family, has traditionally been used as a medicinal plant in the treatment of headaches, coughs, diarrhea, constipation, warts, worms, and kidney malfunctions. objective: to investigate the foliar application effects of bio-stimulators and bio-fertilizers on morphological and phytochemical traits of basil (ocimum basilicum l.). m...

holy basil (ocimum sanctum) is one of the important medicinal plant belongs to lamiaceae family. in order to evaluate the effect of foliar application of iron on iron and chlorophyll contents and photosynthetic parameters of holy basil, an experiment was conducted at research farm of department of horticultural science, shahid chamran university of ahvaz based on randomized complete block desig...
