a GC/MS analyses of the stem bark oil led to the identification of β-bisabolene and α-bisabolol as the main constituents. The major constituents of the oil were formally derived from 2Z,6E-FPP via the bisabolane skeleton. Double-headed arrows indicate bond linkages, not electron flow. b GC/MS analyses of the leaf oil led to the identification of α- and β-pinenes and limonene as the more abundant constituents. They are built up through the menthane and pinane skeletons
