摘要:

The rhizomes ofHedychium coronarium(Zingiberaceae) have yielded two new diterpenes which have been identified by spectroscopic methods, notably long-range heteronuclear coupling (HMBC). Coronarin-D methyl ether is a labdane diterpene typical of those previously isolated from this species. The second compound, identified as 14,15,16-trinorlabda-8(17),11-(E)-dien-13-al, appears to be an unusual trinorditerpene catabolite which could be formed by degradation of the normal labdanes produced by this species.
