ABSTRACT
The oil from seeds of Dipteryx alata Vogel, Fabaceae, popularly known as baru, was extracted by hydraulic and continuous screw pressing. A total of eleven chemical constituents obtained by hydraulic pressing, including steroids, mono and sesquiterpenes and tocopherol derivatives were identified by gas chromatography–tandem mass spectrometry (GC–MS). Compounds limonene, β-elemene, γ-elemene, α-caryophyllene, β-caryophyllene, campesterol, stigmasterol, β-sitosterol and cycloartenol are being described for the first time in the baru oil.
