摘要： Ten new cembrane-type diterpenoids, namely xishaglaucumins A-J (1-10), along with ten known related ones (11-20), have been isolated from the soft coral Sarcophyton glaucum collected off the Xisha Island in the South China Sea. Their structures were elucidated by extensive spectroscopic analysis, quantum mechanical nuclear magnetic resonance (QM-NMR) methods, X-ray diffraction analysis, chemical methods and comparison with the reported data in the literature. The absolute configuration of new compounds 1, 5 and known compounds 11, 12, 16 and 20 were determined either by chemical methods or by X-ray diffraction analysis using Cu K alpha (lambda = 1.5417 angstrom). In in vitro bioassay, compound 4 exhibited inhibitory effects on lipopolysaccharide (LPS)-induced inflammatory responses in BV-2 microglial cells. [GRAPHICS]
