The oleoresins of several Copaifera species have been shown to be rich sources of clerodane, kaurane, and labdane triterpenoids (Figure 1, Figure 2 and Figure 3, Table 2). In particular, C. langsdorffii resin is composed of biologically active copalic acid  and kaurenoic acid . C. multijuga  and C. paupera  resins are also good sources of copalic acid.
