The essential oils obtained by steam distillation from fresh leaves of four Plinia species were analysed by GC–FID and GC–MS. Fifty‐two compounds were identified, accounting for 83.9–98.0% of the total oil. The four Plinia species were characterized by the dominance of sesquiterpenes, especially oxygenated sesquiterpenes. For P. edulis , β ‐caryophyllene and its oxide, caryophyllene oxide, were present in high percentage (39.3%), followed by spathulenol (11.9%). P. trunciflora oil showed β ‐caryophyllene (8.2%), bicyclogermacrene (10.6%), globulol (10.8%) and γ ‐muurolene (9.2%) as the main components. The oil of P. cauliflora was dominated by spathulenol (27.2%), caryophyllene oxide (21.6%) and epi ‐globulol (8.1%) and that of P. cordifolia was especially characterized by compounds with a bisabolane nucleus, such as α ‐bisabolol oxide A (28.0%), α ‐bisabolol oxide B (7.0%) and α ‐bisabolol (5.8%). This last species also showed a high percentage of β ‐caryophyllene (15.9%). Copyright © 2006 John Wiley & Sons, Ltd.
