Three new briarane diterpenes, junceellonoids C–E ( 1 – 3 ), along with six known briaranes, junceellin A ( 4 ), praelolide ( 5 ), and junceellolides A‐D ( 6 – 9 ), were isolated from the EtOH/CH 2 Cl 2 extracts of the South China Sea gorgonian coral Junceella fragilis. The structures of 1 – 3 were established by extensive spectroscopic analysis, including 1D‐ and 2D‐NMR data. Compounds 1 and 2 exhibited mild cytotoxicity against human galactophore carcinoma (MDA‐mB‐231 and MCF‐7) cells at the concentration of 100 μ M .
