摘要：

The roots of Excoecaria agallocha yielded four new diterpenoids, ent-3beta,20-epoxy 3alpha,6alpha-dihydroxykaur-16-ene (agallochin F) (1), 3beta,20-epoxy-3alpha-hydroxybeyer-15-ene (agallochin G) (2), 3beta,20:15R,16S-diepoxy-3alpha-beyeranol (agallochin H) (3), and 3beta,20-epoxy-3alpha,6alpha-dihydroxy-18-nor-beyer-15-ene (agallochin I) (4), along with three known derivatives, 2-acetoxy-1,15-beyeradiene-3,12-dione (5), 2-hydroxy-1,15-beyeradiene-3,12-dione (6), and ent-kauran-16beta-ol-3-one. The structures of 1-4 were determined by spectroscopic (NMR and MS) data interpretation.
