Abstract The leaf oils of two varieties of Eucalyptus camaldulensis growing in Nigeria were analyzed by GC and GC/MS. The quantitatively significant constituents in die leaf oil of the two E. camaldulensis varieties were Î²-pinene (9.0â17.5%), 1,8-cineole (32.8â70.4%), (Z)-Î²-ocimene (11.6%) and Î±-pinene (8.8%). Monoterpenoids also made up the bulk of the two volatile oils (89.0â95.7%).
