3-Benzylmenadiones were obtained in good yield by using a blue-light-induced photoredox process the presence of Fe(III), oxygen, and γ-terpinene acting as hydrogen-atom transfer agent. This methodology is compatible with wide variety diversely substituted 1,4-naphthoquinones well various cheap, readily available benzyl bromides excellent functional group tolerance. The benzylation mechanism was...

The kinetics of antibacterial activity cajuput oil (Melaleuca cajuputi) to E. coli, B. cereus, and S. aureus were investigated. aim this study was determine the reaction orders as an agent. extraction conducted by water-steam distillation. yield 0.88%. GC-MS analysis showed that contained β-ocimene (19.35%), 1.8-cineole (17.67%), limonene (12.09%), β-caryophyllene (9.51%), γ-terpinene (8.93%), ...

The literature shows that the monoterpenes are great candidates for the development of new drugs for the treatment of various pathological processes, including painful conditions. The gamma terpinene (γ-TPN) is a monoterpene present in plant species that have multiple pharmacological properties and has structural similarity to antinociceptive monoterpenes, such as limonene and alpha-phellandren...

Neuropeptide Y (NPY) is an inhibitory neuromodulator expressed abundantly in the central nervous system that is suspected of being an endogenous antiepileptic agent that can control propagation of limbic seizures. Electrophysiological and pharmacological data suggest that these actions of NPY are mediated by G protein-coupled NPY Y2 and NPY Y5 receptors. To determine whether the NPY Y5 receptor...

The Canadian Entomologist 132: 183 195 (2000) Monoterpenes affected the attraction of three sympatric species of bark beetles (Coleoptera: Scolytidae) to pheromone-baited multiple-funnel traps in stands of lodgepole pine. Catches of Ips pini (Say) in traps baited with its pheromone, ipsdienol, were directly related to the release rates of 3-carene, pphellandrene, and ppinene. Catches of Dendroc...

Essential oils from roots, flowers, fruits, and leaves plus stems of Angelica sinensis cultivated in Vietnam were obtained by hydrodistillation analyzed using GC/MS-FID. In total, 36, 30, 33, 27 compounds found accounting for 98.7%, 98.8%, 99.2%, 100% the compositions, respectively. (Z)-Ligustilide (49.4%, 29.6%, 25.8%, 28.9%) γ-terpinene (20.6%, 38.5%, 35.5%, 44.2%) main components respective ...

The volatile and flavonoid compositions of the peel of Citrus medica L. var. Corsican fruits cultivated in Corsica were studied according to the maturity of the citron fruits measured using growing degree-days. Quantitative variation with the stage of development of the fruit was observed using gas chromatography, gas chromatography-mass spectrometry, and liquid chromatography-mass spectrometry...
