25. Efeito antinociceptivo do monoterpeno (S)-(-)-álcool perílico em camudongos
Essential oils are natural products with different applications, especially in the area therapeutic and cosmetic. Many essential oils exhibit a variety of pharmacological properties level of CNS, such as anxiolytic, anticonvulsant and antinociceptive. The influence of functional groups in the structures of these molecules in relation to psychopharmacological

28. Phytochemical and biological evaluation of eucalyptus essential oil / CaracterizaÃÃo fitoquimica e efeito tripanosomicida de Ãleos essenciais de eucalipto
Eucalyptus species are often used for reforestation in Brazil for their phenotypic plasticity and ability to acclimate in response to several environmental conditions. About 20 species are cited due to their chemical diversity in essential oil production. Species are divided into three groups according to their final usage: 1) oils for medical purposes show

29. Essential oils of Mentha pulegium and Mentha rotundifolia from Uruguay
Óleos essenciais obtidos por hidrodestilação das folhas de Mentha pulegium L. e Mentha rotundifolia (L.) Huds. do Uruguay foram analisados por GC-FID e GC-MS. O grupo de monoterpenes oxigenados foi o mais importante em ambos os óleos, sendo que a pulegona, isomenthona e menthona foram os constituintes maioritarios no óleo de Mentha pulegium, no entanto,

31. Effect of inhaled menthol on citric acid induced cough in normal subjects.
BACKGROUND--Menthol is a commonly used ingredient in many over the counter cough remedies, but there is little objective evidence as to its efficacy. METHODS--Twenty healthy subjects received a cough challenge consisting of five inhalations of 33 mumol citric acid from an air driven dosimeter. The challenge was repeated at hourly intervals for five hours. Fi

33. Monoterpene Metabolism. Cloning, Expression, and Characterization of Menthone Reductases from Peppermint1
(−)-Menthone is the predominant monoterpene produced in the essential oil of maturing peppermint (Mentha x piperita) leaves during the filling of epidermal oil glands. This early biosynthetic process is followed by a second, later oil maturation program (approximately coincident with flower initiation) in which the C3-carbonyl of menthone is reduced to yie

34. Metabolism of Monoterpenes 12: EVIDENCE FOR COMPARTMENTATION OF l-MENTHONE METABOLISM IN PEPPERMINT (MENTHA PIPERITA) LEAVES
Previous studies have shown that the monoterpene ketone l-[G-3H]-menthone is reduced to the epimeric alcohols l-menthol and d-neomenthol in leaf discs of flowering peppermint (Mentha piperita L.), and that a portion of the menthol is converted to menthyl acetate while the bulk of the neomenthol is transformed to neomenthyl-β-d-glucoside (Croteau, Martinkus

35. Transient receptor potential melastatin 8 channel involvement in the regulation of vascular tone
The transient receptor potential melastatin 8 (TRPM8) channel has been characterized as a cold and menthol receptor expressed in a subpopulation of sensory neurons but was recently identified in other tissues, including the respiratory tract, urinary system, and vasculature. Thus TRPM8 may play multiple functional roles, likely to be in a tissue- and activat

36. Metabolism of Monoterpenes: Conversion of l-Menthone to l-Menthol and d-Neomenthol by Stereospecific Dehydrogenases from Peppermint (Mentha piperita) Leaves 12
The monoterpene ketone l-menthone is specifically converted to l-menthol and l-menthyl acetate and to d-neomenthol and d-neomenthyl-β-d-glucoside in mature peppermint (Mentha piperita L. cv. Black Mitcham) leaves. The selectivity of product formation results from compartmentation of the menthol dehydrogenase with the acetyl transferase and that of the neome
