Abstract

The essential oils obtained by steam distillation of the leaves, stem bark, stem wood, root bark, root wood and fruits of Siparuna guianensis were analyzed using a combination of GC/MS, retention indices and ¹³C-NMR spectroscopy. Epi-α-cadinol was the major component (11.9–39.9%) in almost all oils, except for the fruit and stem bark oils that contained 2-undecanone (52.7%) and terpinolene (33.3%) as main constituents, respectively.
