Composition of the essential oils from leaves of Piper lepturum Kunth (C.DC.) var. lepturum and Piper lepturum var. angustifolium (Miq.) Yunck. from Brazil
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. β-Guaiene (29.96%) was the principal component in the essential oil of P. lepturum var. lepturum and β-Bisabolene (17.72%) was the principal components in the essential oil of P. lepturum var. angustifolium
