Abstract

Steam distillation of fresh leaves, small rhizomes, large rhizomes and roots of Curcuma cochinchinensis Gagnep. (Zingiberaceae) produced oils in yields of 0.17%,0.21%,0.23% and trace, respectively. The oils were analyzed by high resolution GC and GCIMS. Among the more than 45 compounds identified in the leaf oil, curdione (33.9%) and 1,8-cineole (26.3%) were found to predominate. The oils of the small rhizomes, large rhizomes and roots contained great amounts of oxygenated terpenes such as cis-B-elemenone (11.0%, 14.5% and 13.3%), germacrone (3.8%, 11.3% and 4.3%) and curdione (9.8%, 8.4% and 2.5%). The root oil also contained 1,8-cineole (13.4%) as major constituent. The oxygenated compounds contribute to the special odor of these oils.
