-"The essential oil composition of Cedrela odorata L. leaves was comprehensively investigated by means of capillary GC and GC–MS. Twenty-six constituents were identified in the volatile oil. Sesquiterpenoids such as α-santalene (9.5%), β-acoradiene (7.1%), β-elemene (6.8%), caryophyllene oxide (6.0%) and Z-α-bergamotene (6.0%) were the dominant compounds. Minor constituents included isocaryophyllene, β-bisabolene, β-alaskene and amorpha-4, 11-diene. A rare sesquiterpenoid sulphur derivative, mintsulphide, was identified for the first time in C. odorata essential oil." \\

-The major componentsof the bark oil of C.odorata, collected by hydrodistillation, "... were the sesquiterpene hydrocarbons  β-elemene (20.3%), germacrene D (15.4%), and β-acoradiene (7.0%), along with the  sesquiterpene  alcohol 1,10-di-epi-cubenol (7.2%). C.odorata bark oil from Brazil was also dominated by sesquiterpenoids, but with a very different composition: (E)-caryophyllene (17.2%), (Z)-caryophyllene (9.1%), cis-4(14),5-muuroladiene (10.5%), and lesser amounts of β-elemene (5.4%) and germacrene D (0.4%)." \\

In contrast, the wood oil from Colombia was dominated by δ-cadinene (53%), along with germacrene D (4%)."
