 +"The assessment of enantiopure chiral compounds through Es-GC-O, along with direct olfactive analyses, confirmed that the leaves are a potential substituent for wood in the extraction of Brazilian rosewood essential oil, representing a sustainable nonwood source of natural linalool."​ \\

 +"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."​ \\

 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%). \\ 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.
