Claims
-
Melvin Calvin noted in 1980 that Copaifera oleoresin was being used as diesel fuel directly from the tree with minimal processing. He published further on hydrocarbon fuel plants in 1983 and 1986. Plantations of Copaifera trees were established in Manaus, Brazil in the 1980s to test biofuel viability but were later redirected toward timber and pharmaceutical oleoresin production as diesel prices fell.
-
The oleoresin of Copaifera langsdorffii is composed of a volatile sesquiterpene fraction and a non-volatile diterpene acid fraction. Beta-caryophyllene is the dominant sesquiterpene, comprising up to 53% of the oleoresin in C. langsdorffii. African Copaifera species produce a hardening copal resin rather than the liquid oleoresin characteristic of New World species, due to lower sesquiterpene concentrations.
-
The oleoresin functions in constitutive and induced plant defense. Seedlings of C. langsdorffii have higher sesquiterpene concentrations than parent trees and showed 48% mortality of oecophorid moth larvae reared on their leaves, compared with no mortality on parent-tree leaves.
