By Heather E. Villanueva, Jessika A. Tuten, William A. Haber, William N. Setzer
The pale yellow volatile oil from the bark of Cedrela odorata from Monteverde, Costa Rica, was obtained by hydrodistillation and analyzed by gas chromatography – mass spectrometry. The bark oil was dominated by sesquiterpenes: β-elemene (20.3%), germacrene D (15.4%), 1,10-di-epi-cubenol (7.2%), and β-acoradiene (7.0%). C. odorata bark essential oil was screened for antimicrobial activity and showed appreciable activity against the Gram-positive bacterium Bacillus cereus and the mold Aspergillus niger.
