Abstract: A novel cembrane-type diterpenoid was first isolated from the soft coral Sarcophyton crassocaule collected from the Xisha Islands in the South China Sea. Its structure was determined on 2D-NMR, HRMASS and IR techniques and the relative configuration was confirmed by NOESY and X-ray diffraction. The crystaLIs monoclinic, space group P21 with cell dimensions of a=0.890 00(10) nm, b=0.638 0(10) nm, c=1.169 670(2) nm. α=90°, β=92.470(10)°, γ=90°, V=0.926(3) nm3, D=1.192 4 g/cm3, Z=2, R=0.057 8, wR=0.138 0. The new compound was named as Sarcocrassolide B. It exhibited a strong cytotoxicity against P388 cell line with IC50 value of 1.5 μg/mL.

Key words: Soft coral, Sarcophyton crassocaule, Sarcocrassolide B
