Copaifera L. is one of the most economically important plant genera in the Amazon Region, since it exudes a resin-oil named copaiba oil possessing several confirmed pharmacological properties. In spite of that, phytochemical studies of the seeds from this genus are rare. Copaifera officinalis L. was the first species in the genus Copaifera to be described. This paper describes the chemical composition of the hexane and ethyl acetate extracts of the seeds from this species. In the hexane extract, gas chromatography and mass spectrometry analyses enabled us to identify squalene, tetradecane, hexadecane, campesterol, stigmasterol and beta-sitosterol; hexadecanoic, 9-octadecenoic and octadecanoic acids (major substances); as well as decanoic, eicosanoic, docosanoic and tetracosanoic (minor substances) acids. Coumarin was detected in the ethyl acetate extract, isolated and identified by NMR.
