In the troposphere, the fate of gas-phase Criegee intermediates (CIs) is deemed to be determined by their reactions with water molecules. Here it is shown that CIs produced in situ on the surface of water/acetonitrile (W/AN) solutions react competitively with millimolar carboxylic acids. Present experiments probe, via online electrospray mass spectrometry, CIs chemistry on the surface of alpha-humulene and beta-caryophyllene in W/AN microjets exposed to O3(g) for < 10 micro sec. Mass-specific identification lets us establish the progeny of products and intermediates generated in the early stages of CIs reactions with H2O, D2O, H2O(18), and n-alkyl-COOH (n = 1-7)...

BACKGROUND AND AIMS: Beta-caryophyllene (BCP) is a plant-derived FDA approved food additive with anti-inflammatory properties. Some of its beneficial effects in vivo reported to involve activation of cannabinoid 2 receptors (CB2) that are predominantly expressed in immune cells. Herein, we evaluated the translational potential of BCP using a well-established model of chronic and binge alcohol-induced liver injury. METHODS: In this study we investigated the effects of BCP on liver injury induced by chronic plus binge alcohol feeding in mice in vivo by using biochemical assays, real-time PCR and histology analyses...

Sesquiterpenes emitted from biogenic sources play important roles in atmospheric HOx cycles and new particle formation. Current atmospheric models, however, fail to account for their fates, possibly due to missing heterogeneous sinks. Here we apply interface-specific mass spectrometry to detect carbocation products of the reactive uptake of gaseous sesquiterpenes C15H24 (β-caryophyllene (β-C), α-humulene (α-H), and alloaromadendrene (a-d)) on the surface of aqueous microjets as functions of water acidity and gas concentration...

Beta-caryophyllene (BCP) is a phytocannabinoid whose neuroprotective activity has been mainly associated with selective activation of cannabinoid-type-2 (CB2) receptors, inhibition of microglial activation and decrease of inflammation. Here, we addressed the potential of BCP to induce neuritogenesis in PC12 cells, a model system for primary neuronal cells that express trkA receptors, respond to NGF and do not express CB2 receptors. We demonstrated that BCP increases the survival and activates the NGF-specific receptor trkA in NGF-deprived PC12 cells, without increasing the expression of NGF itself...

Pitnenta is a genus of flowering plants in the Myrtaceae family, which has about 15 species, mostly found in the Caribbean region of the Americas. Commonly used for culinary and medicinal purposes, the best known commercial species are allspice, P. dioica (P. officinalis) and bay rum, P. racemosa, but there is little information concerning P. guatemalensis. The aim of the present study was to identify the chemical composition of the leaf and fruit essential oils ofP. guatemalensis. The extraction of essential oils of P...

REVIEW
Bart Steenackers, Luc De Cooman, Dirk De Vos
The annual production of hops (Humulus lupulus L.) exceeds 100,000 mt and is almost exclusively consumed by the brewing industry. The value of hops is attributed to their characteristic secondary metabolites; these metabolites are precursors which are transformed during the brewing process into important bittering, aromatising and preservative components with rather low efficiency. By selectively transforming these components off-line, both their utilisation efficiency and functionality can be significantly improved...

The present report was designed to determine the antigenotoxic capacity of beta-caryophyllene (BC) on the damage induced by benzo(a)pyrene (BaP) in mouse. We found no genotoxic potential of BC, and a significant inhibitory effect on the number of sister-chromatid exchanges (SCE) and chromosomal aberrations induced by BaP. The three tested doses of the agent (20, 200, and 2,000 mg/kg) produced a dose-dependent decrease of the two evaluated cytogenetic parameters. In comparison with the effect induced by BaP, the best inhibitory effect (about 80%) was obtained with the high tested dose of BC considering the two evaluated parameters...

Beta-caryophyllene (BCP) and docosahexaenoic acid (DHA) are components of several plants with documented anti-inflammatory and analgesic effects in animal pain models. In the present study, in vitro and in vivo tests were carried out to evaluate their effects, alone or in combination, during long-lasting administration in a model of persistent pain. IR spectra of the two compounds were obtained to determine their chemical stability and then in vitro toxicity was evaluated in fibroblasts and astrocytes. In the in vivo tests, the analgesic effects of BCP and BCP+DHA were determined in male rats subjected to a model of persistent recurrent pain (three repetitions of the formalin test once a week) to mimic recurrent pain...

Beta-caryophyllene (BCP) is a natural bicyclic sesquiterpene and is a FDA approved food additive, found as an active ingredient in essential oils of numerous edible plants. It possesses a wide range of biological activities including anti-oxidant, anti-inflammatory, anti-cancerous and local anesthetic actions. We used the well established Caenorhabditis elegans model system to elucidate the stress modulatory and lifespan prolonging action of BCP. The present study for the first time reports the lifespan extension and stress modulation potential of BCP in C...

The amount and chemical composition of essential oils are crucial for the modulation of the flavor, scent and therapeutic properties of aromatic and medicinal plants. The aim of this study was to evaluate the effects of phenology and weather conditions on the essential oil yield obtained from the aerial parts of Salvia lavandulifolia Vahl. Besides, we tried to carry out an approach to the chemical composition at the time of full bloom. Essential oil production of several accessions was monitored throughout the whole phenological cycle, both, at the original location growing wild and at the experimental plot as cultivated plants...
