Two new diterpenoids, junceellonoids A and B ( 1 and 2 , resp.), together with the seven known diterpenoids 3 – 9 , all possessing the briarane carbon skeleton, were isolated from the gorgonian Junceella fragilis Ridley , collected in the South Sea of China. The structures and relative configurations of the new metabolites were elucidated based on extensive spectral analysis and by comparison with known spectral data.
