Abstract

Three new sesquiterpenes, isozedoarondiol (8), methylzedoarondiol (9) and neocurdione (10), were isolated along with germacrone (1), curdione (2), (4S, 5S) -germacrone 4, 5-epoxide (3), dehydrocurdione (4), procurcumenol (5), zedoarondiol (6) and curcumenone (7) from Curcuma aromatica SALISB. The absolute configuration of 6 was determined by X-ray analysis and chemical correlation with 3. The structures of 8, 9 and 10 were also determined.
