Abstract(s)
Os óleos essenciais despertam cada vez mais o interesse da comunidade científica pelas
suas características. São cada vez mais utilizados na indústria de cosméticos, farmacêutica, entre outras.
Neste trabalho, foi feito um estudo dos óleos essenciais da laranja e do limão. A extração destes óleos foi feita através do processo de hidrodestilação em aparelho de Clevenger, do qual resultou um rendimento aceitável.
Os óleos essenciais foram caracterizados por cromatografia gasosa agrupada à
espectroscopia de massa.
Foram identificados dez componentes nos óleos essenciais da laranja e do limão, onde o limoneno é o componente maioritário.
Avaliou-se ainda a atividade ótica, a partir da qual se calculou a rotação específica e os
resultados comparados com os tabelados foram concordantes para o óleo essencial da laranja, mas não o foram para o óleo essencial do limão.
Essential oils arouse increasing interest of the scientific community for its characteristics. They are increasingly used in cosmetics, pharmaceuticals, among others. In this work, a study was made of essential oils of orange and lemon. The extraction of these oils was done through the process of hydrodistillation in Clevenger apparatus, which resulted in an acceptable income. The essential oils were characterized by gas chromatography mass spectroscopy on pooled. We identified ten components in the essential oils of orange and lemon, where the limonene is the major component. It was also evaluated the activity viewpoint, from which the specific rotation was calculated and compared with the tabulated were concordant for the essential oil of orange, but were not for the essential oil of lemon.
