Abstract The chemical composition of the volatile concentrates of the flowers of Couroupita guianensis, Lecythis usitata var. paraensis and Eschweilera coriacea were examined by GC/MS. The major components identified in the flowers of C. guianensis were linalool (21.5%), eugenol (18.9%) and (E,E)-farnesol (16.1%). The main constituents of the flowers of L. usitata var. paraensis were 2-phenylethyl alcohol (40.8%), phenylacetaldehyde (28.2%) and linalool (22.1%). The flowers of E. coriacea were dominated by (E)-Î²-ocimene (23.4%) and hexanal (11.6%).
