Abstract Essential oils of rice flower, Ozothamnus diosmifolius, were analyzed by capillary gas chromatography-mass spectrometry. Flower oil contained Î²-pinene (28.4%) and 1,8-cineole (28.2%), while the leaf oil contained Î±-pinene (26.0%), Î²-pinene (11.6%) and 1,8-cineole (22.2%). Both oils had small amounts of spathulenol (4.1% and 5.2%, respectively).
