Abstract:
Steam distillation of fresh roots, small rhizomes, large rhizomes, stems and leaves of Curcuma elata Roxb (Zingiberaceae) produced oils in yields of 0.25%, 0.26%, 0.34%, 0.02%, 0.19% repectively. The oils were analyzed by high resolution GC and GC/MS. Among the more than 40 compounds identified in the stem and leaf oils-pinene (9.1% and 9.7%) 1.8-cineole (17.8%; 21.9%) and humelene (7.5% and 6.7%) we found predominatly. The oils of the roots, small rhizomes and large rhizomes contained great amounts of oxygenated terpenes such as ar-curcu-mene (22.3%, 26.7% and 25.4%), bisabolene (14.7%, 16.9% and 15.9%) and cuzerenone (20.6%, 13.9% and 12.0%). The oxygenated compounds contribute to the special odor of these oils.
