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.
从莪术(Curcuma aromatica
SALISB)中分离出了三种新的
倍半萜,即异莪术二醇(isozedoarondiol)(8)、甲基莪术二醇(methylzedoarondiol)(9)和
新莪术二酮(neocurdione)(10),以及
莪术酮(germacrone)(1)、
莪术二酮(curdione)(2)、(4S,5S)-
莪术酮 4,5-
环氧化物(3)、脱氢
莪术二酮(dehydrocurdione)(4)、
莪术醇(procurcumenol)(5)、莪术二醇(zedoarondiol)(6)和
莪术酮(curcumenone)(7)。通过 X 射线分析和与 3 的
化学相关性确定了 6 的绝对构型,还确定了 8、9 和 10 的结构。
