| The aim of this study was to investigate the effect of dietary supplementation with Cymbopogon flexuosus essential oil (EO) on productive performance, metabolic parameters and body and fillet composition of adult silver catfish, Rhamdia quelen. Total length, condition factor, weight gain, specific growth rate, hepatosomatic index, visceral fat content and fillet composition were not affected by EO supplementation. Plasma total protein, globulin and triglycerides were reduced by EO supplementation. Supplementation with 1 mL EO kg-1 diet increased carcass yield and protein deposition in the carcass, while reducing gonadosomatic index and fat deposition in the carcass when compared to control group. In addition, 1 mL EO kg-1 diet also improved feed intake... |

| Several volatile natural compounds produced by plant secondary metabolism have been proven to present antimicrobial action, enabling their use in phytopathogen control. They also present low environmental impact when compared to conventional pesticides. Essential oils contain these compounds and can be found in several plant species, such as Lippia alba (Mill.) N.E. Brown (Verbenaceae). Essential oils of four chemotypes of L. alba, characterized by their major compounds, namely camphor, citral, linalool and camphor/1,8-cineole, were tested against the phytopathogen Alternaria solani Sorauer (Pleosporaceae), which causes early blight on tomatoes and is responsible for great economic losses regarding production. Essential oils antifungal action was tested in... |

| Superficial mycoses of the skin are among the most common dermatological infections, and causative organisms include dermatophytic, yeasts, and non-dermatophytic filamentous fungi. The treatment is limited, for many reasons, and new drugs are necessary. Numerous essential oils have been tested for both in vitro and in vivo antifungal activity and some pose much potential as antifungal agents. By using disk diffusion assay, we evaluated the antifungal activity of lemongrass oil and citral against yeasts of Candida species (Candida albicans, C. glabrata, C. krusei, C. parapsilosis and C. tropicalis). This study showed that lemongrass oil and citral have a potent in vitro activity against Candida spp. |

| Lippia alba is empirically used for infusions, teas, macerates, and hydroalcoholic extracts because of its antispasmodic, analgesic, sedative, and anxiolytic effects. Citral is a mixture of trans-geranial and cis-neral and is the main constituent of L. alba essential oil and possesses analgesic, anxiolytic, anticonvulsant, and sedative effects. The present study evaluated the effects of the essential oil of L. alba (EOLa) and citral on compound action potentials (CAPs) in Wistar rat sciatic nerves. Both drugs inhibited CAP in a concentration-dependent manner. The calculated half-maximal inhibitory concentrations (IC50) of peak-to-peak amplitude were 53.2 µg/mL and 35.00 µg/mL (or 230 µM) for EOLa and citral, respectively. Peak-to-peak amplitude of the CAP... |

| Abstract This study optimized using a headspace solid-phase microextraction (HS-SPME) method for extracting volatile aroma compounds, terpenoids in particular, from Litsea mollis Hemsl. immature fruit (LMIF). Gas chromatography-mass spectrometry was used to separate and identify volatile terpenoids in LMIF. The types of SPME fiber coating, salt addition, and desorption time were optimized by single factor-experiments to determine the range of extraction temperature. Built on insights from the single factor-experiments, the response surface methodology was further used to optimize the extraction temperature, extraction time, and equilibrium time of HS-SPME. The results showed that the optimal HS-SPME conditions for extracting volatile terpenoids from LMIF... |

| A utilização de malhas fotoconversoras para o cultivo de algumas espécies ornamentais e olerícolas tornou-se comum. Diante da grande influência que a radiação solar exerce sobre os vegetais, esta pesquisa foi realizada com o objetivo de avaliar o efeito da intensidade e da qualidade espectral da luz transmitida pelas malhas fotoconversoras (Chromatinet®) em relação a aspectos fisiológicos de crescimento (teor, rendimento e composição química) do óleo essencial de Melissa officinalis L. Em delineamento inteiramente casualizado, foram dispostos quatro tratamentos e cinco repetições, sendo cada parcela composta de quatro vasos (uma planta por vaso). Os tratamentos foram caracterizados por plantas de melissa cultivadas a pleno sol, em malha preta (50%), em... |

| ABSTRACT: The aim of this study was to investigate the anesthetic effect of the essential oils (EOs) of Lippia alba (citral and linalool chemotypes, EOLA-C and EOLA-L respectively) and Lippia origanoides (chemotype carvacrol, EOLO-Ca) on tambaqui (Colossoma macropomum) juveniles. The tested concentrations of the L. alba and L. origanoides EOs were: 25, 50, 100, and 200 μL/L. Time required to reach the stages of sedation, deep anesthesia, and recovery, as well as ventilatory frequency, were monitored for each EO concentration. The results indicated that all EO concentrations tested induced tambaqui anesthesia and that the ventilatory frequency was altered by the EOs. L. origanoides showed the shortest time to induce sedation and anesthesia, but had long... |

| The objective of this study was to investigate the effect of vermicompost, worm-bed leachate (WBL) and Glomus mosseae, an arbuscular mycorrhizal fungi (AMF), on growth of lemongrass (Cymbopogon citratus (DC.) Stapf). A response surface methodology, i.e. a three-level Box Benhen design with three repetitions and three blocks, was applied to optimize biomass production, essential oil yield and its composition. Application rates of Glomus mosseae were 0, 1 or 2 g plant-1, vermicompost 0, 5 or 10 g plant-1 and WBL 0, 10 and 20%. The AMF had no significant effect on the variables tested, but vermicompost had a significant effect on essential oil yield and WBL on essential oil yield, myercene concentration and shoot dry weigh (p < 0.05). It was found that... |

| RESUMO: Objetivou-se avaliar o efeito das malhas fotoconversoras e épocas de colheita no crescimento, produção de biomassa, teor e composição química do óleo essencial de manjericão (Ocimum basilicum var. citriodorum). O experimento foi conduzido na área experimental da Universidade Tecnológica Federal do Paraná, Campus Dois Vizinhos. Foram estudadas quatro épocas de avaliação (90, 120, 150 e 180 dias após o transplantio) e três malhas fotoconversoras (malha aluminizada, malha vermelha, malha preta e pleno sol), todas com 50% de irradiância. Os tratamentos foram arranjados em esquema fatorial 4x4, com parcelas subdivididas, no delineamento experimental blocos ao acaso, com três repetições. O cultivo sob malha aluminizada favoreceu o crescimento em altura e... |

| Com o objetivo de avaliar o comportamento agronômico, o potencial de rendimento de óleo essencial e identificar os quimiotipos de 16 acessos de Lippa alba (erva cidreira) da coleção da Universidade de Brasília foi conduzido um experimento de campo em Latossolo Vermelho, sob irrigação por gotejamento na região do Cerrado do Distrito Federal. Foram avaliados a época de florescimento, hábito de crescimento, área foliar, comprimento da haste, massa fresca de folhas e hastes, massa foliar seca, teor e rendimento de óleo essencial e perfil aromático. O óleo essencial foi extraído por hidrodestilação em aparelho de Clevenger modificado e os constituintes identificados e quantificados através de cromatografia em fase gasosa acoplada a espectrometria de massas.

| O cidró (Aloysia triphylla) é uma planta medicinal de porte arbustivo, com folhas aromáticas que possuem óleo essencial rico em citral, e essa substância confere grande importância à indústria farmacêutica e cosmética. Objetivou-se avaliar o teor e os componentes do óleo essencial do cidró em função da sazonalidade e horário de colheita. O experimento foi conduzido na área experimental da Universidade Tecnológica Federal do Paraná, Campus Dois Vizinhos, de março de 2010 a setembro de 2011. O delineamento experimental utilizado foi de blocos ao acaso em esquema fatorial onde os fatores foram realizados nas épocas de extração (outubro/2010 a setembro/2011) e horários de colheita (8:00, 11:00, 14:00, 16:00 e 18:00 horas). Foram analisados o teor e composição... |
