-"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." \\
+"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." \\
