A novel clovane-type sesquiterpenoid derivative, rumphellclovane B (1), which possesses an unprecedented δ-lactone moiety, and a new natural clovane, 9α-hydroxyclovan-2-one (2), were isolated from the gorgonian coral Rumphella antipathies. The structures of clovanes 1 and 2 were elucidated by interpretations of spectral data. A plausible biosynthetic pathway between these two compounds was proposed. Compound 1 displayed inhibitory effects on superoxide anion generation by human neutrophils.
