ABSTRACT

The essential oils of Brazilian Piper lepturum var. lepturum and Piper lepturum var. angustifolium (Piperaceae) were obtained by hydrodistillation and analyzed by flame-detector gas chromatography (GC) and gas chromatography coupled to mass spectrometry (GC/MS). According to GC and GC/MS analysis, the essential oils are mostly composed by sesquiterpenes hydrocarbons. beta-Guaiene (29.96 percent) was the principal component in the essential oil of P. lepturum var. lepturum and beta-Bisabolene (17.72 percent) was the principal components in the essential oil of P. lepturum var. angustifolium.


Los aceites esenciales de las especies brasileñas Piper lepturum var. lepturum y Piper lepturum var. angustifolium fueron obtenidos por hidrodestilación y analizados utilizando cromatografía gas líquido con detector de ionización de llama (CG) y cromatografía gas líquido acoplada a un detector de masas (CG/EM). De acuerdo con los análisis de CG y CG/EM, los aceites esenciales muestran como componente principal beta-Guaieno (29,96 por ciento) en el aceite esencial de P. lepturum var. lepturum y beta-Bisaboleno (17,71 por ciento) en el aceite esencial de P. lepturum var. angustifolium.
