The leaf essential oils of the seven Australian members of the genus Rhodomyrtus have been examined. Rhodomyrtus canescens C. T. White & W. D. Francis produced an oil in which the main components were α‐pinene (20–23%), β‐pinene (6–10%) and aromadendrene (12–17%). R. effussa Guymer produced an essential oil that was completely sesquiterpenoid in character, the principal components being globulol (11–22%), viridiflorol (8–10%) and spathulenol (5–18%). R. macrocarpa Benth. also produced an essential oil that was dominated by sesquiterpenes. The principal components were β‐caryophyllene (9–44%), aromadendrene (6–11%), and globulol (8–10%). The major components of R. pervagata Guymer essential oil were α‐pinene (27–35%) and β‐pinene (18–24%). R. psidioides (G. Don.) Benth. also produced an essential oil which was monoterpenoid in nature. The principal components were α‐pinene (28–66%) and limonene (1–24%). The oil from R. sericea Burret. contained α‐pinene (28%), β‐pinene (21%) and β‐caryophyllene (13%) as principal components. The two subspecies of R. trineura both were essentially sesquiterpenoid in character. In R. trineura (F. Muell.) F. Muell. ex Benth. subsp. trineura the major components were β‐caryophyllene (16–29%), caryophyllene oxide (2–12%) and globulol (7–10%), while in R. trineura subsp. capensis Guymer a more variable oil was obtained with some samples containing significant amounts of the monoterpene α‐pinene. The major components detected in the oil were α‐pinene (tr–26%), globulol (9–19%), viridiflorol (5–12%) and spathulenol (4–7%). © 1997 John Wiley & Sons, Ltd.
