Abstract

The chemical compositions of the essential oils from the leaves of Piper aduncum from Panama and Bolivia were investigated by GC‐FID, GC‐MS and ^13^C‐NMR. In total, 55 components were identified representing 99.3 and 80.3% of each sample, respectively. The oil from Panama was characterized by a high percentage of sesquiterpene hydrocarbons (38.9%), the main ones being β‐caryophyllene (17.4%) and aromadendrene (13.4%). In contrast, the oil from Bolivia showed a high content of monoterpenes (76%), the major constituent being 1,8‐cineole (40.5%). Phenylpropanoids, mainly sarisan (1‐allyl‐2‐methoxy‐4,5‐methylenedioxybenzene; 12.9%), were only detected in the latter. Copyright © 2004 John Wiley & Sons, Ltd.
