Abstract The chemical composition of the volatile concentrates of the flowers of Wulffia baccata and Zinnia elegans were analyzed by GC/MS. The major components identified in the flowers of W. baccata were (E)-(Î²-ocimene (17.3%), limonene (136%), germacrene D (13.0%) and myrcene (11.8%). Germacrene D (12.4%) and p-cymene (9.1%) were the major components found in the flowers of Z. elegans.
