 [The chemical composition of some Lauraceae essential oils and their antifungal activities. Simić, A., Soković, M. D., Ristić, M., Grujić‐Jovanović, S., Vukojević, J., Marin, P. D., Phytotherapy Research, Vol.18(9), 2004, 713-717]
-Bois de rose oils from French Guiana (Cayenne type) own a higher content of (-)-(R)-linalool than Brazilian oils, this may have been the reason why Cayenne type oils were considered as superior. An analysis of the wood scent (SPME-GC/MS) showed the main constituents to be linalool (49.1%), α-terpineol (21.3%), limonene (6.8%), and terpinolene (6.1%). \\

+"For a given tree, a decreasing yield gradient was observed from trunk wood to branches, smaller branches, and leaves. Linalool percentage in oil ranged from 73–99%. All trunk wood oils contained a percentage of (-)-linalool close to 100%, except for two trees from Paracou station where a low proportion of (+)-linalool was present. Oils from small branches contained from 5–28% of (+)-linalool. All leaf oils showed a high percentage (78–89%) of (+)-linalool. The linalool form in oil from shoot, bark and root samples was purely (-)-linalool. Measures performed on different parts of the same tree showed that the linalool from trunk wood and thick branches was purely (-)-linalool, whereas the proportion of (+)-linalool increased with the thinness of the branches and reached 85% in leaves." \\
