Résumé
The chemical composition of leaf oils from Campomanesia aurea, C. guazumifolia, C. rhombea and C. xanthocarpa (Myrtaceae) were analyzed by GC and GC/MS. Sixty-two compounds have been identified ranging from 94-99% of the oil contents. Our results showed that all analyzed species were rich in sesquiterpenes, among them spathulenol (27.7%) and !b-caryophyllene oxide (29.0%) in C. guazumifolia; bicyclogermacrene (13.6%) and globulol (10.8%) in C. rhombea; and (E)-nerolidol (28.8%) in C. xanthocarpa. The monoterpene fraction was well represented in C. aurea (40.3%), with predominance of the α-pinene (16.5%) and myrcene (11.5%), besides C. rhombea and C. xanthocarpa that showed an important amount of linalool (9.7% and 17.2%, respectively).
