| Abstract:
The essential oils of the leaves and twigs of two chemotypes of Melaleuca teretifolia Endl growing wild in Western Australia were investigated by GC and GC/MS. One chemical form which yielded 0.2% on a fresh weight basis was found to be rich in 1,8-cineole (84.0%) with  -pinene (1.8%),  -pinene (1.2%), limonene (3.1%), terpinen-4-ol (1.8%) and -terpineol (3.3%) as the only other significant constituents.
The lemon form gave a much higher yield (1.5%) of an oil rich in neral (29.1%), geranial (38.8%), and myrcene (9.8%) with significant concentrations of limonene (1.0%), citronellal (1.0%), terpinen-4-ol (3.4%), geraniol (2.1%), nerol (1.1%), Z-isocitral (1.6%) and E-isocitral (2.4%). The potential commercial value of these oils as medicinal and aromatic plant products is discussed.
