Some compounds present in the wood of Torresia acreana Ducke (Leguminosa, Lotoideae) were identified. Coumarin, vanillic acid, the terpenoids campesterol, stigmasterol, sitosterol, cycloeucalenol, 24-methylene cicloartanol and cycloartenol and some fatty acids chiefly oleic, palmitic and linoleic acids had their presence established by chromatographic and spectrometric methods. The allelopathy of these compounds was discussed.
