Further New Secoatisane Diterpenoids from the Chinese MangroveExcoecaria agallocha L.

Abstract

Four new 3,4-seco-ent-atisane diterpenoids, agallochaols G–J (1–4), were isolated from the stems and leaves of the Chinese mangrove Excoecaria agallocha L. Their structures were established on the basis of detailed spectroscopic analysis, chemical evidence, and by comparison with the literature data of related compounds.
