Volatile constituents of two species of Protium from the Atlantic rainforest in the state of Pernambuco, Brazil.
The chemical composition of the essential oils from Protium giganteum and P. aracouchine was determined, for the first time, using GC-MS analysis. From the oil of P. giganteum, 32 components were identified, representing 93.9% of the oil, and from P. aracouchine, 29 components, representing 97.8% of the oil. Among the compounds identified in the P. giganteum oil, 93.6% were sesquiterpenes, with beta-caryophyllene (26.0 +/- 0.8%), globulol (9.3 +/- 0.2%), alpha-cadinol (7.0 +/- 0.5%), alpha-humulene (6.4 +/- 0.1%) and germacrene D (6.2 +/- 0.3%) as the major components. Among the 29 compounds identified in the P. aracouchine oil, 95.9% were sesquiterpenes as well, with spathulenol (31.8 +/- 1.6%), alpha-cis-bergamotene (8.8 +/- 0.2%) and viridiflorol (9.7 +/- 0.7%) as the major components.
