ABSTRACT

Essential oils obtained from the aerial parts of Dicypellium manausense, Mezilaurus duckei, Mezilaurus itauba and Pleurothyrium vasquezii collected at the Ducke Forest Reserve (Manaus, Brazil) were obtained by hydrodistillation and analyzed by CG-FID and GC-MS. Essential oil yields ranged from 0.1 to 0.2 percent (w/w of dry material). The major components were beta-caryophyllene in the leaves of D. manausense (39.5 percent), leaves and branches of M. duckei (32.6 and 18.4 percent, respectively) and branches of M. itauba (51.8 percent); and germacrene D in the leaves of D. manausense (6.7 percent), branches of M. itauba (9.1 percent) and leaves and branches of P. vasquezii (15.6 and 8.0 percent, respectively). This paper describes for the first time the composition of these essential oils.


Os óleos essenciais obtidos das partes aéreas de Dicypellium manausense, Mezilaurus duckei, Mezilaurus itauba e Pleurothyrium vasquezii coletadas na Reserva Florestal Ducke (Manaus, Brasil) foram obtidos por hidrodestilação e analisados por CG-DIC e CG-EM. Os rendimentos dos óleos variaram de 0,1 a 0,2 por cento (m/m de material seco). Os principais componentes foram beta-cariofileno nas folhas de D. manausense (39,5 por cento), folhas e galhos de M. duckei (32,6 e 18,4 por cento, respectivamente) e galhos de M. itauba (51,8 por cento) e germacreno D na folhas de D. manausense (6,7 por cento), galhos de M. itauba (9,1 por cento) e folhas e galhos de P. vasquezii (15,6 e 8,0 por cento, respectivamente). Este trabalho descreve pela primeira vez a composição desses óleos.
