Cymbopogon, Nanopartículas, Compostos FitoquímicosResumo
Justificativa e Objetivos: O gênero Cymbopogon sp. tem despertado interesse devido aos seus compostos bioativos compotencial antifúngico e antimicrobiano. Este estudo investigou a atividade antifúngica in vitro do óleo essencial de Cymbopogon flexuosus livre e nanoemulsionado contra cepas padrão ATCC de Candida spp. Métodos: Foram utilizadas no ensaio as cepas de: Candida albicans, Candida tropicalis, Candida Krusei e Candida glabrata, comparadas a um controle positivo (Fluconazol e Anfotericina B) e controle negativo (água destilada+Tween 80 a 2%). A técnica utilizada foi de difusão em ágar. Após o tratamento, os ensaios foram incubados a 36°C, por 48 horas, sendo realizados com seis repetições. Resultados: No ensaio foi observada atividade antifúngica para todas as cepas ATCC testadas. O óleo livre nas concentrações de 10, 15 e 70% foi semelhante ao controle positivo para Candida tropicalis. A concentração de 5% do óleo nanoemulsionado apresentou resultado semelhante ao controle positivo para Candida glabrata. Conclusão: Entre as espécies testadas, a Candida albicans mostrou ser mais sensível em todas as concentrações; a Candida krusei foi a cepa mais resistente para o uso de óleo essencial. Novos estudos, de cunho toxicológico e clínico, são necessários para complementar nossos achados.
