Abstract
The oleoresins of Copaifera paupera, C. piresii and C. pubiflora were examined by GC-FID and GC/MS. The oleoresins of C. paupera and C. piresii were characterized by a high percentage of α-copaene (42.5% and 45.5%), followed by β-caryophyllene (14.1% and 10.3%) and δ-cadinene (10.4% and 13.7%, respectively). The oleoresin of C. pubiflora was dominated by β-caryophyllene (65.9%).
