“…Pinene exerted supraspinal antinociceptive actions (Liapi et al, 2007). β-Caryophyllene exhibited antinociceptive effect (Menezes et al, 2007) and anti-inflammatory activity in several experiments (Guan et al, 2007;Fu et al, 2007).…”

RESUMO: "Óleos essenciais encontrados na fumaça do ¨tira-capeta¨, um cigarro utilizado pelos quilombolas que vivem no pantanal do Brasil". Pesquisa etnofarmacológica realizada entre os quilombolas que vivem na Sesmaria Mata-Cavalos, no Estado de Mato Grosso, Brasil, um cigarro conhecido como ¨tira-capeta¨, foi citado por melhorar a memória e cognição, além de possuir outras indicações terapêuticas, tais como, "contra a sinusite", "para evitar resfriado", e "para aliviar problemas de insônia". No presente estudo, foi feita a caracterização dos óleos essenciais liberados durante o aquecimento das plantas utilizadas na confecção do cigarro, usando um método simples, rápido e livre de solvente baseado em cromatografia gasosa acoplada a espectrometria de massas usando "headspace" e microextração em fase sólida. Os principais constituintes encontrados foram 1,8-cineol, cânfora e α-pineno. Na tentativa de correlacionar a atividade biológica desses constituintes com as indicações terapêuticas relatadas pelos quilombolas, encontramos vários trabalhos realizados por diversos autores que mostraram que estes óleos possuem atividades similares às indicações terapêuticas relatadas pelos quilombolas.Unitermos: Etnofarmacologia, óleos essenciais, medicina popular, sistema nervoso central, quilombolas, memória. ABSTRACT: An ethnopharmacological survey developed among quilombolas living in SesmariaMata-Cavalos, in the State of Mato Grosso, Brazil; a cigarette known as "tira-capeta" (removingthe-devil), had been cited mainly "to improve memory and cognition", and also showed other therapeutical indications, such as: "against sinusitis", "to avoid cold", "to relieve sleep problems". The purpose of the present study was carried out a screening of essential oils delivered in the heating of plants used to produce the "tira-capeta" cigarette, using a simple, rapid and solvent-free method based on gas chromatography-mass spectrometry and headspace solid-phase microextraction. The principal essential oils found were 1,8 cineole, camphor and α-pinene. In the tentative to correlate these constituents with therapeutical indications reported by the quilombolas, were found some works carried out by many authors that corroborated the therapeutical indications reported by the quilombolas.

Abstract. Indonesia is the largest clove producer in the world. In 2012, total world clove production is 113,215 tons where nearly 71 % (79,250 tons) comes from Indonesia. Although Indonesia is a major producer of clove in the world, research and publications about cloves in this country are scarce and hence knowledge about characteristics of difference varieties of cloves is very limited. The present study was aimed to compare major and minor constituents in clove oil responsible for their flavor based on origin which are cloves from Toli-Toli and Bali. The clove bud oil was isolated from clove bud (Syzygium aromaticum) using steam distillation. The compounds of clove bud oil was analyzed using GC-MS. The major compounds of clove oil were eugenol, caryophyllene, α-humulene and eugenyl acetate with composition 66.37 %, 15.38 %, 1.97 % and 12.99 %, respectively (Toli-Toli) and clove from Bali were 72.34 %, 12.51 %, 2.34 % and 5.33 %, respectively. The unique minor compounds of clove oil from Toli-Toli were (+)-δ-cadinene (0.13 %) and β-caryophylladienol (0.19 %) while in clove oil from Bali were valencene (0.17 %), δ-selinene (0.22 %) and alloaromadendrene (0.24 %). A total of 36 compounds were identified from the clove bud oil Toli-Toli and 38 compounds from the clove bud oil Bali.

“…It is well known that with the increase of pressure, the density of SCF-CO 2 increases, and the solubility of solute increases. The extraction yield enhances significantly with the increase of pressure, due to the increase of the solubility of the oil components (Guan et al, 2007). This is attributed to the increase of the CO 2 density, which results in the increase of its dissolving ability.…”

Supercritical fluid extraction (SFE) is one of the most commonly used extraction techniques in the course of analysis or preparation. It is environmentally friendly and has some advantages over other conventional extraction methods. This review covers the recent developments of SFE in the extraction of essential oils from the plant materials during the period 2005 to 2011, in particular some factors influencing SFE extraction yield, its characteristics and applications.
