Three new bisabolane sesquiterpenoids, bisacurone (1__∼), bisacumol (2__∼) and bisacurol (3__∼), and one kown compound, curlone (4∼), were isolated from the rhizomes of Curcuma xanthorrhiza__- (Zingiberaceae). The absolute structures of these new compounds were determined by spectroscopy, chemical conversions and the exciton chirality method for allylic alcohols.
