The four Australian members of the genus Uromyrtus have been examined for their essential oils. U. australis A. J. Scott gave an oil in 0.12% yield (all yields are quoted on a fresh weight basis) in which sesquiterpenes accounted for over 95% of the oil. The principal components were β‐caryophyllene (21%) and γ‐, α‐ and β‐eudesmol (13, 9 and 11% respectively). Uromyrtus metrosideros (F. M. Bailey) A. J. Scott gave an oil in 0.15–0.3% yield of which over 50% were monoterpenes. The principal components were α‐pinene (13–20%) and β‐pinene (33–42%). Other components of significance were α‐terpineol (3–7%) and spathulenol (9–15%). Uromyrtus sp. (Tinaroo Range G. P. Guymer 2034) produced an oil in 0.1–0.2% yield which was basically devoid of monoterpenes. The major components were bicyclogermacrene (14–23%), globulol (9–12%), viridiflorol (5–7%) and spathulenol (3–4%). Uromyrtus sp. (McPherson Range G. P. Guymer 2000) gave an oil in 0.4–0.8% yield which contained a significant proportion of monoterpenes. The principal components were terpinen‐4‐ol (8–13%) and α‐pinene (3–10%).
