The OH oxidation of α-pinene under both lowand high-NOx environments was studied in the Caltech atmospheric chambers. Ozone was kept low to ensure OH was the oxidant. The initial α-pinene concentration was 20–50 ppb to ensure that the dominant peroxy radical pathway under low-NOx conditions is reaction with HO2, produced from reaction of OH with H2O2, and under high-NOx conditions, reactions wi...

objective: eucalyptus (fam. myrtaceae) is a medicinal plant and various eucalyptus species possess potent pharmacological actions against diabetes, hepatotoxicity, and inflammation. this study aims to investigate essential oil compositionfrom leaves and flowers of e. microthecaand e. viminalisleavesgrowing in the southeast of iran. materials and methods: the aerial parts of these plants were co...

The formation of secondary organic aerosol (SOA) from both ozonolysis and hydroxyl radical (OH)-initiated oxidation of α-pinene under conditions of high nitric oxide (NO) concentrations with varying relative humidity (RH) and aerosol acidity was investigated in the University of North Carolina dual outdoor smog chamber facility. SOA formation from ozonolysis of α-pinene was enhanced relative to...

prangos ferulacea (apiaceae) is a perennial herb with a distribution from east europe to middle east and central asia. the plant’s leaves are used as animal fodder. its fruits and roots possess biological traits that provide it with the potential to be used for medicinal purposes. the essential oils obtained through hydrodistillation from aerial parts of prangos ferulacea at the vegetative and ...

background and objectives: parkinson's disease (pd) is a common neuropathologic disorder that is caused by degeneration of dopaminergic neurons of dense part of nigra. oxidative stress has been found in the pathophysiology of pd. since α-pinene has strong anti-oxidant effects, the purpose of this research was to study its effects on movement disorders and memory and lipid peroxidation in p...

BACKGROUND Contrary to other Tephritidae, female but also male olive flies, Bactrocera oleae release pheromones during their sexual communication. Alpha-pinene, a common plant volatile found in high amounts in unripe olive fruit and leaves has been detected as one of the major components of the female pheromone. However, possible effects of α-pinene and that of other host volatiles on the matin...

The objective of the present study was to characterize essential oil Myrciaria tenella (MTEO) leaves, determine effects distillation time (1 5 h), and evaluate its action on acute pain inflammation both in vivo vitro. MTEO obtained by hydrodistillation for 4 h 36 compounds were detected, mainly consisting hydrocarbon terpenes such as β-pinene (21.46%), α-pinene (19.43%), E-caryophyllene (10.89%...

The essential oils associated with the flowers of Tithonia diversifolia (Hemsl.) A. Gray were extracted and characterized via hydrodistillation and Gas Chromatography. Hydrodistillation was done in an all-glass Clevenger-type apparatus. The extracts from the hydrodistillation were subjected to gas chromatography where the components of the essential oils were separated based on their molecular ...
