The fresh rhizomes of Curcuma xanthorrhiza ROXB. were investigated for terpenoids and curcuminoids. Nine sesquiterpenoids, a-curcumene (1), arturmerone (2), xanthorrhizol (3), germacrone (4), β-curcumene (6), β-sesquiphellandrene (9), curzerenone (10), α-turmerone (11) and β-turmerone (12), and three curcuminoids, curcumin (7), mono-demethoxycurcumin (8) and bis-demethoxycurcumin (13), were isolated and one monoterpenoid, camphor (5), was identified by capillary GC-MS. Four species of C. xanthorrhiza could be classified into two chemotypes by their bisabolane-type sesquiterpenoid compositions. The first type contained large amounts of 2,11 and 12 (CX I type). The second type contained large amounts of 1,3 and 6,and none of 2,9,11 and 12 (CX 11 type). These two chemotypes, CX I type and CX II type, were compared with the two chemotypes of C. longa L., CL I type and CL II type, on their contents by capillary GC and HPLC analysis. It was found that all of them contained curcuminoids, 7,8 and 13 and large amounts of various bisabolane-type sesquiterpenoids.
