Summary
The continuity of resewood oil production in Amazonia is not assured, due to difficulties in propagation and slow growth of Aniba duckei Kosterm. With the purpose of solving this old problem, two lines of research were pursued: 1. The analysis (including seasonal variation of composition) of rosewood leaf (yield 2-2.5%, and buranch (yield 1-1.7%) oil, obtained from A. duckei Kosterm. (Lauraceae). 2. A survey of common amazonian plants for linalool content, which led td the discovery of sacaca leaf oil (yield 0.8%), obtained from Croton cajuçara Benth. (Euphorbiaceae), containing over 66% linolool.
