Spondias tuberosa Arruda (Anacardiaceae) is an endemic tree in the Caatinga Brazilian Biome, known locally as "umbuzeiro" and used for various purposes, especially as food and folk medicine. In this study, it was realized for the first time, the extraction and characterization by gas chromatography-mass spectrometry (GC-MS) of the fixed oils of barks, leaves and stems of S. tuberosa. The constituents of the oils were identified by comparing the mass spectra obtained with those of the equipment database. The major component of fixed oil obtained from barks was the 3-n-Pentadecylphenol (44.91 %), in the leaves and stems was observed presence of the tetratetracontane (38.17 and 28.57%, respectively). Antioxidant activity was evaluated by using 2,2-diphenyl-1-picrylhydrazil (DPPH) radical scavenging and β-carotene-linoleic acid bleaching test. The fixed oil obtained from the leaves presented the best antioxidant activity (51.13%±11.8) in β-carotene-linoleic acid bleaching test. This study described for the first time identification and quantification of the components present in the fixed oils of the bark, leaves and stems of Spondias tuberosa.       Key words: Natural products, fatty acids, gas chromatography-mass spectrometry (GC-MS), antioxidant.
