Abstract
The chemical compositions of the essential oils from rhizomes of Curcuma aromatica cultivated in Japan and India were analyzed by GC and GC/MS. These oils were extremely
different. The major constituents in both oils from Japanese samples were curdione,
germacrone, 1,8-cineole, (45,5S)-germacrone-4,5-epoxide, β-elemene, and linalool,
whereas those in the oil from Indian were β-curcumene, ar-curcumene, xanthorrhizol, germacrone, camphor, and curzerenone.
