Tempo de destilação e perfil volátil do óleo essencial de aroeira da praia (Schinus terebinthifolius) em Sergipe

Abstract

The fruits and essential oils of Brazilian pepper (Schinus terebinthifolius) have antimicrobial activity against gram-positive bacteria, as well as anti-inflammatory action. The essential oil of Brazilian pepper is used to treat fungal infections, and its antifungal activity is attributed to the high concentration of monoterpenes. This study aimed to determine the best yield of distillation of the essential oil of seeds and leaves of Brazilian pepper and the chemical components of the essential oil in different periods of distillation. One hundred grams of each material were distilled in Clevenger apparatus for 2.5 h, 4.0 h, 5.5 h and 7.0 h. The distilled material was analyzed by gas chromatography coupled to mass spectrometer, where the chromatographic profile of the material was obtained. Seeds of Brazilian pepper showed higher amounts of essential oils when compared with the leaves in all the periods of distillation. The essential oil of Brazilian pepper showed a profile consisting mainly of volatile mono- and sesquiterpenes.
