The essential oils of Curcuma tonga L. (Zingiberaceae) were isolated from its rhizomes and leaves by hydrodistillation. The oils were analyzed by high resolution GC and GC/MS. The rhizome oils contained more than 40 constituents, of which the major ones were ot-turmerone (30-32%), ar-turmerone (17-26%) and beta-turmerone (15-18%). The leaf oil contained about 60 compounds and the main constituents were alpha-phellandrene (18.2%), 1,8-cineole 04.6%) and p-cymene (13.3%).
