Two new diterpenoids, anthogonoid A and antsimplexin A (1–2), as well as a known diterpenoid, klysimplexin G (3), were isolated from a Beibu Gulf gorgonian coral, Anthogorgia caerulea. The structures of these compounds have been established by detailed spectroscopic analysis and by comparison with spectral data of related known compounds. Compounds 1–3 showed significant antifouling activity against the larval settlement of Balanus amphitrite.
Key words: Anthogorgia caerulea, Diterpenoid, Antifouling Activity
