The majority oleoresins from Pará possessed high amounts of β-bisabolene (18.4–42.4%) and trans-α-bergamotene (11.8–29.6%). The oleoresins from Amapá were rich in β-caryophyllene (27.8–68.0%), β-selinene (0.2–20.6%) and β-bisabolene (3.7–17.8%). The results showed a high variation in the composition of the components of the oleoresins of C. reticulata.

Seasonal variation in the volatiles of copaifera duckei dwyer growing wild in the state of pará - Brazil / Osmar A. Lameira in The journal of essential oil research, Vol. 21 N° 2+ supplément vol.20 (Mars/Avril 2009+ supplément 2008)

The highest oleoresin harvested from Sample A occurred at October 2003 to May 2004 (in the later dry season to early rainy season); the highest oleoresin harvested from Sample B occurred at September and October 2003 (in the later dry season), and from Sample C in June (in the later rainy season). The percentage of the major volatiles of the oleoresin of Samples A and C (Sample A: β-caryophyllene, trans-α-bergamotene, β-selinene and β-bisabolene; Sample C: β-caryophyllene and β-bisabolene) changes in a minor extent during the seasons. However, appreciable changes were observed from the percentage of β-caryophyllene and β-bisabolene in the Sample B. In the same way, appreciable changes were observed on the amount of oleoresin harvested: Sample A: 10 mL to 500 mL, Sample B: zero to 3000 mL, Sample C: zero to 70 mL. In conclusion, for the all samples of C. duckei studied here, we observed considerably changes in the amount of oleoresin harvested. Nevertheless, the percentage of the main components of Samples A and C were not affected in a great extent. Contrary, the Sample B, the percentage of the major compounds changes considerably during seasons.

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%).
