Cyclic monoterpenes are a group of phytochemicals with antinociceptive, local anesthetic, and anti-inflammatory actions. Effects of cyclic monoterpenes including vanilin, pulegone, eugenole, carvone, carvacrol, carveol, thymol, thymoquinone, menthone, and limonene were investigated on the functional properties of the cloned α7 subunit of the human nicotinic acetylcholine receptor expressed in X...

Protium is the most frequent genus of Burseraceae in Adolpho Ducke Forest Reserve (Manaus, Amazonas), which where its species were previously identified and mapped this has favored various studies central Amazon forest. A number P. divaricatum Engl., opacum Swart strumosum Daly trees selected with objective providing information about their chemical biological aspects. Resin exudation was stimu...

In this study, we were interested in the valuation of Ocimum gratissimum, an aromatic and medicinal plant Ivorian flora. The essential oils leafy branches gratissimum extracted by hydrodistillation with a Clévenger-type device. yield obtained increases from (0.05±0.01%) to (0.42±0.08%) depending on drying time. density is almost constant at 0.80. chemical composition was identified after analys...

In arctic and subarctic regions, rapid climate changes enhance biogenic volatile organic compound (BVOC) emissions from vegetation, with potentially significant influence on atmospheric processes. However, the seasonal diel patterns of bidirectional exchange (flux) BVOCs remain poorly studied in these regions. Here, we deployed a proton-transfer-reaction time-of-flight mass spectrometer (PTR-TO...

Terpenes are compounds that include monoterpenes, sesquiterpenes, diterpenes, and terpenes, where isoprene is the basic structural unit of multiple oxygenated hydrocarbons. often found in plants, especially some Zingiberaceae or tulips, they have been obtained by direct extraction, chemical synthesis, microorganisms. They exhibit anti-bacterial, anti-viral, anti-oxidant, analgesic activity, aid...

Aromatic plants and essential oils have many applications in medicine, pharmaceuticals, cosmetics, the food industry. The oil of flowering aerial parts Achillea grandifolia, obtained by hydrodistillation, was analyzed for its constituents investigated antimicrobial radical scavenging activity. characterized a high amount oxygenated monoterpenes (72.7%) with 1,8-cineole (29.2%) camphor (23.4%) b...

Secondary metabolites from plant organisms have always been excellent options for the pharmaceutical, cosmetic, and food industries. Essential oils are a type of found in vegetables, their chemical composition is diverse; however, monoterpenes sesquiterpenes inside most abundant molecules. These terpenes diverse that range simple molecule with carbon hydrogen to more complex molecules oxygenate...

L. stoechas subsp. luisieri is one of the five spontaneous species genus Lavandula that occurs spontaneously in Portugal. The chemical profile and antifungal activity essential oils were investigated. oil two phenological stages was isolated by hydrodistillation their components analyzed GC-FID/GC-MS. minimum inhibitory concentration (MIC) fungicidal (MFC) both determinate to verify against dif...
