“…Os óleos essenciais vegetais são compostos basicamente pelos terpenos e fenilpropanóides, os quais apresentam propriedades antifúngicas e antimicrobianas comprovadas (Benkeblia, 2004;Rehder et al, 2004;Almeida et al, 2006;Arruda et al, 2006;Nunes et al, 2006;Perini et al, 2011).…”

Essential oils are alternative to control pathogenic agents, agricultural pests and weeds, with the use of pesticides in agriculture has been an important tool in the control of many pathogenic microorganisms and plants to increase production, but the indiscriminate use of these chemicals has negatively affected the environment and human health. It has been researched lately, demand for new plants with metabolic molecules such as terpenes, alkaloids and phenolic compounds, in effect; bioinsecticide, biofungicide bioherbicida and plants that can replace chemicals or with low or no residual power and reduce the impact to environment, this manuscript aims to give a comprehensive explanation on the importance of essential oils and their secondary metabolites in plant defense. The use of plants with insecticidal properties, fungicide and herbicide, shows a high potential of this tool in the management of pests, diseases and weeds. For the final insertion and safe botanical products in agriculture, however, more studies are still needed.

“…In this situation, interest in plants with antifungal properties has increased as a consequence of current problems associated with the antifungal therapy. Since antiquity, medicinal plants have been used to treat common infectious diseases and the essential oils of these plants have been widely used in the treatment of infectious pathologies in many body parts including skin (23, 29). …”

Trichophyton rubrum is one of the most common fungi causer of dermatophytosis, mycosis that affect humans and animals around the world. Researches aiming new products with antifungal activity become necessary to overcome difficulties on treatment of these infections. Accordingly, this study aimed to investigate the antifungal activity of essential oil from Cymbopogon winterianus against the dermatophyte T. rubrum. The antifungal screening was performed by solid medium diffusion method with 16 T. rubrum strains, minimum inhibitory concentration (MIC) and minimum fungicide concentration (MFC) were determined using the microdilution method. The effects on mycelial dry weight and morphology were also observed. Screening showed essential oil in natura inhibited all the tested strains, with inhibition zones between 24-28 mm diameter. MIC50 and MIC90 values of the essential oil were 312 μg/mL for nearly all the essayed strains (93.75 %) while the MFC50 and MFC90 values were about eight times higher than MIC for all tested strains. All tested essential oil concentrations managed to inhibit strongly the mycelium development. Main morphological changes on the fungal strains observed under light microscopy, which were provided by the essential oil include loss of conidiation, alterations concerning form and pigmentation of hyphae. In the oil presence, colonies showed folds, cream color and slightly darker than the control, pigment production was absent on the reverse and with evident folds. It is concluded that C. winterianus essential oil showed activity against T. rubrum. Therefore, it could be known as potential antifungal compound especially for protection against dermatophytosis.

RESUMO:Os dados obtidos na literatura sobre a atividade antimicrobiana dos óleos essenciais são tratados do ponto de vista experimental, considerando-se uma possível aplicação clínica dos óleos. O presente estudo teve como objetivo analisar os fatores que infl uenciam na atividade antimicrobiana de óleos essenciais, in vitro, com base nos resultados descritos na literatura. Foi verifi cado que os testes e avaliações da atividade antimicrobiana dos óleos essenciais podem ser difi cultados pela volatilidade do óleo, sua insolubilidade em água e sua complexidade química. Tais difi culdades tornam os resultados disponíveis na literatura, difíceis de comparar. Por outro lado, os métodos usados diferem largamente e fatores importantes que infl uenciam os resultados são freqüentemente negligenciados. Assim, após breve levantamento, concluiu-se que alguns fatores devem ser levados em consideração, tais como: a técnica usada, o meio de cultura, densidade do inóculo, o óleo essencial e o emulsifi cador utilizado. Portanto, para a realização de testes que visam verifi car a atividade antimicrobiana de óleos essenciais, é necessário defi nir e adotar uma metodologia adequada e bem padronizada.Unitermos: Óleo essencial, atividade antimicrobiana, métodos.ABSTRACT: "Antimicrobial activity of the essentials oils: a multifactor approach of the methods". The given data of the literature on the antimicrobial activity of the essential oils are treated from the experimental point of view, and they consider a possible clinical application of the oils. The purpose of this study is to analyze the factors that can infl uence on antimicrobial activity of essential oils, in vitro, based on preview data from literature. We noticed that the tests and evaluations of the antimicrobial activity of the essential oils can be hindered by the volatility of the oil, its insolubility in water and its chemistry complexity. These details make the results obtained on literature diffi cult to compare. The used methods differ broadly and important factors that infl uence the results are frequently neglectful. After a bibliographical rising, we concluded that a large attention should be given to some factors when we work with essential oils: the used technique, the growth medium, the inoculums density, the tested essential oil and the used emulsifying. It's necessary to defi ne and follow a right and standard methodology to make antimicrobial activity testes of essential oils.Keywords: Essential oil, antimicrobial activity, methods.
