Two new avermectin derivatives, avermectins B 1c and B 1e ( 1 and 2 , resp.), as well as two known compounds, avermectin B 2a ( 3 ) and ivermectin A 1a ( 4 ), were isolated from a Beibu Gulf gorgonian coral, Anthogorgia caerulea. The structures of the new compounds were established by detailed spectroscopic analysis and by comparison with spectral data of related known compounds. Compounds 1 – 4 showed moderate antifouling activities against the larval settlement of Balanus amphitrite.
