| Popis: | Aos frutos e óleos essenciais da aroeira da praia (Schinus terebinthifolius) atribui-se atividade antimicrobiana sobre bactérias gram positivas além de ação anti-inflamatória. O óleo essencial da aroeira é utilizado no tratamento de micoses, sendo a sua atividade antifúngica atribuída à alta concentração de monoterpenos. Este estudo teve como objetivo determinar o melhor rendimento de destilação de óleo essencial de sementes e folhas da aroeira e os componentes químicos do óleo essencial nos diversos períodos de destilação. Cem gramas de cada material foram destilados em aparato de Clevenger durante 2,5h, 4,0h, 5,5h e 7,0h. O material destilado foi analisado por cromatografia a gás acoplada a espectrofotômetro de massas, onde foi obtido o perfil cromatográfico do material. As sementes de aroeira apresentaram maiores quantidades de óleo essencial, quando comparadas com as folhas em todos os períodos de destilação. O óleo essencial de aroeira mostrou perfil volátil formado principalmente por mono e sesquiterpenos. 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. |
