In global greening, biogenic volatile organic compound (BVOC) emissions and their influencing factors have been considered due to significant roles in the biosphere atmosphere. Many studies reported relationships of BVOC with environmental plant ecophysiology. However, direct indirect effects on remain unclear, causal between ecophysiology are ambiguous. We measured isoprene monoterpene from do...

Many monoterpenes have been identified in forest emissions using gas chromatography (GC). Until now, it has been impossible to determine whether all monoterpenes are appropriately measured using GC techniques. We used a proton transfer reaction mass spectrometer (PTR-MS) coupled with the eddy covariance (EC) technique to measure mixing ratios and fluxes of total monoterpenes above a ponderosa p...

The first enantioselective synthesis of (-)-paeonilide is reported. Starting from inexpensive furan-3-carboxylic acid the targeted monoterpene was obtained in 12 steps via an asymmetric cyclopropanation-lactonization cascade and a stereoselective side chain insertion at an acetal-like position.

Benzene is a volatile chemical implicated in leukemia and hepatic injury through oxidative stress-mediated mechanism. Linalool naturally small molecular monoterpene with proven antioxidant pro...

cDNA cloning of a monoterpene synthase from Perilla frutescens whose steam-distilled oil contains 92.9% perillaketone, was performed by the PCR method using primers designed based on limonene synthase. The full-length nucleotide sequence of this cDNA consisted of 1978 bp including a 1827-bp translational region encoding a deduced protein of 608 amino acids, which was similar to that of limonene...

dracocephalum kotschyi (lamiaceae), as one of the remarkable aromatic plants, widely grows and also is cultivated in various temperate regions of iran. there are diverse reports about the composition of the oil of this plant representing limonene derivatives as its major compounds. there is no report on cloning of mono- or sesquiterpene synthases from this plant. in the present study, the aroma...
