Each tree yields about 1% oil by weight of wood... A. rosodora is an endangered species. Populations have declined rapidly due to the destructive harvesting methods. Areas previously logged have not seen much regrowth. It might even be critically endangered." |

+ | "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, | ||
