„Freshly cut heartwood is pinkish to reddish brown, but upon exposure it becomes red or dark reddish brown, sometimes with a purplish tinge. It is reported to be darkest when grown in the drier regions. The sapwood is whitish, gray, or pinkish…
A gum-like substance containing a volatile aromatic oil exudes from Spanish cedar. The oil often stains the paper lining in cigar boxes made of this wood, and when it evaporates it leaves a sticky residue that causes boards to adhere.“

„Cedrela odorata is the most commercially important and most widely distributed species in the genus Cedrela. Known as Spanish cedar in English commerce, the aromatic wood is in high demand in the American tropics because it is naturally termite- and rot-resistant…
Cedro heartwood contains an aromatic and insect-repelling resin that is the source of its popular name, Spanish cedar (it resembles the aroma of true cedars).“
[Cedrela odorata L. Cedro hembra, Spanish cedar. Cintron, Barbara B., Silvics of North America 2(654) 1990, 250]

„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%).“
