First phytochemical description of essential oils from Piper cachimboense (Piperales, Piperaceae)
ABSTRACT Piper cachimboense is recorded only for the Amazon region of Brazil and Colombia, and the objective of this study was to report the first phytochemical assessment of the composition of the essential oils (EOs) from this species collected in the Amazon rainforest, in Novo Progresso, Pará State, Brazil. Samples of leaves were subjected to hydrodistillation in a Clevenger-type apparatus. The chemical identification was carried out by gas chromatography. The yield of oils was of 11.03 ± 5.94% for fresh leaves, and 1.07 ± 0.27% for dry leaves. The analysis showed 36 volatile compounds from fresh leaves and 49 from dried leaves. Main constituents in EOs of both fresh and dried leaves from P. cachimboense were (E)-caryophyllene, germacrene-D, γ-amorfene, δ-cadinene and apiole.
