1. The anticonvulsant effects of Ducrosia anethifolia (Boiss) essential oil are produced by its main component alpha-pinene in rats
RESUMO A Ducrosia anethifolia tem sido recomendada como remédio para os distúrbios neurológicos. No entanto, os efeitos anticonvulsivantes do óleo essencial de Ducrosia anethifolia (DAEO) e do seu principal constituinte atfa-pineno (α-pineno) ainda não foram clarificados. Métodos: Foi utilizado um modelo de rato de convulsões induzidas por pentileno

2. Essential oil from Ageratum fastigiatum reduces expression of the pro-inflammatory cytokine tumor necrosis factor-alpha in peripheral blood leukocytes subjected to in vitro stimulation with phorbol myristate acetate
Abstract Ageratum fastigiatum (Gardner) R.M. King & H. Rob., a member of the Asteraceae family popularly known in Brazil as "matapasto", is indicated in folk medicine as anti-inflammatory and analgesic. Despite its popular use, little is known about its potential effect on the parameters involved in an inflammatory response. The objective of this study was t

3. Evaluation of antianxiety and sedative effects of essential oil of Ducrosia anethifolia in mice
INTRODUCTION: We investigated the antianxiety and sedative effects of the essential oil of Ducrosia anethifolia. Boiss. (Apiaceae). METHODS: We used elevated plus maze, spontaneous motor activity and ketamine-induced sleep tests in mice. In addition, the essential oil was analyzed by GC/MS. Twenty compounds were identified, and n-decanal (70.1%) and alpha-pi

4. Estudo do mecanismo de ação antinociceptivo e antiedematogênico do óleo essencial de Croton argyrophylloides e seus constituintes: alfa-pineno e trans-cariofileno / Study of the antinociceptive mechanism of action and antiedematogenic the essential oil of Croton argyrophylloides and its constituents: alpha-pinene and trans-caryophyllene
O Croton argyrophylloides, popularmente conhecido como marmeleiro prateado, é uma espécie nativa da caatinga do Nordeste. O óleo essencial de Croton argyrophylloides (OECa) possui comprovado efeito antinociceptivo e antiedematogênico (Canuto, 2005). O objetivo deste estudo foi elucidar o mecanismo de ação antinociceptivo e antiedematogênic

5. Monoterpenos di-hidroxilados e hidróxi-nitrogenados 1,2 e 1,3 como ligantes quirais em reação de reformatsky assimétrica
This study describes the use of three (-)-alpha-pinene derivatives, one diol-1,2 [(-)-(1R, 2R, 3S, 5R)-2,6,6-trimethylbicyclo[3.1.1]heptane-2,3-diol 4] and two piridine-hydroxy derivatives [(+)-(1R,2S,3R,5S)-2,6,6-trimethyl-3-(2-pyridinylmethyl)bicyclo[3.1.1]heptan-3-ol 7 and (-)-(1R,2S,3R,5S)-2,6,6-trimethyl-3-[2-(2-pyridinyl) ethyl]bicyclo[3.1.1]heptan-3-o

6. Atividade acaricida dos óleos essencias de folhas e frutos de Xylopia sericea sobre o ácaro rajado (Tetranychus urticae Koch)
The essential oils of the leaves and fruits obtained by hydrodistillation of Xylopia sericea, collected in the restinga area of Pernambuco, were analyzed by GC (HP 5890 SERIES II) and GC/MS (HP 5890B SERIES II/ MSD 5971). A major part of the volatile components identified in the oils of fruits and leaves were monoterpenes and sesquiterpenes. Cubenol (57.43%)

7. Pharmacological properties of the monoterpenes α- and β-pinene on rat gastrointestinal smooth muscle: myorelaxant and prokinetic effects / Propriedades farmacolÃgicas dos monoterpenos α- e β-pineno no mÃsculo liso gastrintestinal de ratos: efeito miorrelaxante e prÃ-cinÃtico
α- e β-pineno sÃo monoterpenos constituintes do Ãleo essencial de plantas encontradas no Nordeste do Brasil como a malva-santa e o eucalipto que, na medicina popular, sÃo usadas no tratamento de distÃrbios intestinais e respiratÃrios. As aÃÃes miorrelaxantes desses Ãleos essenciais sÃo atribuÃdas à presenÃa de α- e de β-pineno

8. Production of aromas and fragrances through microbial oxidation of monoterpenes
Aromas and fragrances can be obtained through the microbial oxidation of monoterpenes. Many microorganisms can be used to carry out extremely specific conversions using substrates of low commercial value. However, for many species, these substrates are highly toxic, consequently inhibiting their metabolism. In this work, the conversion ability of Aspergillus

9. Constituintes químicos voláteis e não-voláteis de Cochlospermum vitifolium (Willdenow) Sprengel
The essential oils from leaves, root bark and root wood of Cochlospermum vitifolium were investigated for the first time. The oils were obtained by hydrodistillation and analyzed by GC/MS. The main volatile constituents were beta-caryophyllene (8.2 - 46.5%), beta-bisabolene (11.5 - 29.3%), gamma-muurolene (28.4%), alpha-humulene (26.0%), 1-hydroxy-3-hexadeca

10. Bacterial metabolism of alpha-pinene: pathway from alpha-pinene oxide to acyclic metabolites in Nocardia sp. strain P18.3.
Over 20 gram-positive bacteria were isolated by elective culture with (+/-)-alpha-pinene as the sole carbon source. One of these strains, Nocardia sp. strain P18.3, was selected for detailed study. alpha-Pinene-grown cells oxidized, without lag, alpha-pinene, alpha-pinene oxide (epoxide), and the cis and trans isomers of 2-methyl-5-isopropylhexa-2,5-dienal.

11. Influence of Environmental Factors and Air Composition on the Emission of [alpha]-Pinene from Quercus ilex Leaves.
We studied the emission of [alpha]-pinene from Quercus ilex leaves. Only the abaxial side of the hypostomatous Q. ilex leaf emits [alpha]-pinene. Light induced photosynthesis and [alpha]-pinene emission. However, the response of photosynthesis to dark-to-light transitions was faster than that of [alpha]-pinene, suggesting that ATP controls the emission. The

12. Liquid/air partition coefficients of four terpenes.
The liquid/air partition coefficients of four common terpenes, alpha-pinene, beta-pinene, 3-carene, and limonene, have been determined in vitro using head space technique. The liquids used were water, human blood, and olive oil. alpha-Pinene, beta-pinene, and 3-carene were practically insoluble in water and limonene was slightly soluble; all were readily dis
