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, | ||
