Chemical Variation in the Volatiles of Copaifera reticulata Ducke (Leguminosae) Growing Wild in the States of Pará and Amapá, Brazil

Abstract

The oleoresins of 12 trees of Copaifera reticulata growing wild in the States of Pará and Amapá were examined by GC-FID and GC/MS. 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.
