摘要：

Three novel diterpenoids, excoecarins D, E, and K (1-3), were isolated from Excoecaria, agallocha. The structures of 1-3 were established as 3 alpha,18-dihydroxy-3 beta,20-epoxybeyer-15-ene, (15R,16S)-ent-15,16-epoxybeyerane3-one, and ent-3 beta-hydroxykaur-16-en-2-ane, respectively, on the bash of extensive NMR experiments and, in the case of 1, by X-ray analysis.
