Abstract-The seven Australian species of the genus Tasmannia (pepper bushes) were examined for essential oil
content by steam distillation and solvent extraction. Each species was distinguished on essential oil grounds with
intraspecific variation most obvious with T. membranea and T. insipida. Tasmannia oils were characterized by
monoterpenoids LX- and /3-pinene, limonene, sabinene, a-phellandrene, lS-cineole and linalool; sesquiterpenoids
caryophyllene, bicyclogermacrene, germacrene D, cadina-1,4-diene, calamenene, a-copaene, a-cubebene, elemol, c+!-fi, -
and y-eudesmol and viridiflorol and phenylpropanoids eugenol, safrole and myristicin. The characteristic hot spice
flavour of Tasmannia species was not explained by the volatile constituents.
