Abstract: Four new 8-hydroxybriarane diterpenoids, frajunolides L–O (14), were isolated from the Taiwanese gorgonian Junceella fragilis. The structures of compounds 14 were elucidated based on spectroscopic analysis, especially 2D NMR (1H-1H COSY, HSQC, HMBC and NOESY) and HRMS. Compounds 1 and 4 showed weak anti-inflammatory activity as tested by superoxide anion generation and elastase release by human neutrophil in response to fMLP/CB. Compound 3 showed selective inhibition on elastase release in vitro.
