Abstract The essential oils of three species of Thryptomene native to Queensland were examined. T. hexandra and T. parviflora produced oils in which 1,8-cineole (up to 70%) and Î±-pinene (up to 16%) were the principal components. T. oligandra, from far north Queensland, produced an oil in which Î³-terpinene (32-62%) and p-cymene (25-50%) and Î±-pinene (1-20%) were the main components.
