 "Among the main odorants [of the wood from C.decurrens] found were a series of terpenes, several degradation products of fatty acids, and a number of odorants with a phenolic core moiety. Five odorants are reported here for the first time as wood odorants, such as γ-octalactone and 3-phenylpropanoic acid; thymoquinone was demonstrated for the first time to have a pencil-like odor quality." \\ "Among the main odorants [of the wood from C.decurrens] found were a series of terpenes, several degradation products of fatty acids, and a number of odorants with a phenolic core moiety.
