Abstract
The leaf oils of the Australian members of the genus Pseuduvaria have been examined. Both P. mulgraveana var. mulgraveana and P. mulgraveana var. glabrescens showed extremes in oil composition, with elemicin (87%) and methyl eugenol (61%) being the principal components. Pseuduvaria villosa possessed a sesquiterpenic oil in which the major components were β-caryophyllene (3–13%) and α-copaene (4–11%). In the oil from P. froggattii, the principal components were caryophyllene oxide (2–22%), a fourth dihydroagarofuran isomer (froggatt ether) (0.1–18%), spathulenol (9–18%) and a sesquiterpene alcohol C15H26O (t-20%), while in P. hylandii the major components were β-caryophyllene (22–28%), α-himachalene (2–10%) and α-humulene (8–9%).
