Composição química, atividade antimicrobiana do óleo essencial e ocorrência de esteróides nas folhas de Pterodon emarginatus Vogel, Fabaceae

Resumo

Pterodon emarginatus Vogel, Fabaceae, known as “sucupira-branca”, is a tree specie with interest as medicinal plant and source of wood. Several studies with the oil and fruit’s extracts have been showed cercaricid, antimicrobial and antiinflamatory activities. The importance of P. emarginatus conducted the present study to realize evaluated antifungal and antibacterial activity of essential oil of their leaves, and isolated some compounds of ethanolic extract of the leaves. The analysis of the essential oil from leaves allowed the identification of nine sesquiterpenics hydrocarbons, with the majority γ-muurolene (48.79%) and biciclogermacrene (22.66%). The essential oil showed activity against the Gram-positive bacteria, and inactive on clinical isolates of Candida. The phytochemical study of the ethanol extract of the leaves allowed the isolation of the mixture of stigmasterol and β-sitosterol steroids. All results contribute to the expansion of information about this plant widely used by the population.
