The crude Et2O extract of soft coral Sarcophyton glaucum, collected off the Xisha, the South China Sea, were investigated. A new cembrane-type diterpenoid, namely 15-dehydroxy-sarcophytrol D (1), together with twenty-five known compounds, namely ximaoglaucumin C (2), (11S, 12S, 1E, 3E, 7E)-11, 12-epoxycembra-1, 3, 7-triene (3), sarcophytol W (4), cembrene (5), sarcophytol B (6), sarcophytol K (7), sarcophytol J (8), pentaene-cembrene (9), sarcophytol E (10), (+)-marasol (11), (2S)-sarcophytoninsarcophytoxide (12), (-)-17-hydroxydeepoxysarcophytoxide (13), (+)-sarcophytoxide (14), 13-acetoxysarcophytoxide (15), bophynin B (16), 16-oxosarcophytoxide E (17), sarcophinone (18), 7α-8β-dihydroxydeepoxysarcophine (19), (+)-sarcophine (20), 14-dehydroxy-sarcophytol L (21), sarcophytol L (22), 13α-hydroxy-sarcophytol L (23), trocheliophol C (24), trocheliophol E (25) and trocheliophol L (26), were isolated and purified by comprehensive chromatography methods of silica gel column, Sephadex LH-20 gel column, TLC, and semi-preparative high-performance liquid chromatography (HPLC). In anti-inflammatory bioassay, compound 4 exhibited inhibitory effects on lipopolysaccharide (LPS)-induced inflammatory responses in BV-2 microglial cells.
