Abstract: Headspace volatile analysis has been used for volatiles profiling in leaves of 4 Magnolia species with a total of
75 compounds were identified. Monterpene hydrocarbons dominated the volatile blend of M. calophylla (86%), M.
acuminata (78%), M. virginiana (70%) and M. grandiflora (47%) with β-pinene and β-ocimene occurring in the largest
amounts, whereas sesquiterpenes were the most abundant compounds in M. grandiflora (39%). High levels of
oxygenated compounds were only found in M. virginiana volatile blend (11.4%) with 2-phenylethyl alcohol as major
component. Hierarchical cluster analysis performed on volatiles content revealed the close relationship between M.
acuminata and M. calophylla.
