Abstract:

To investigate the cembranoid diterpenes from the soft coral Sarcophyton sp. collected in the South China Sea. Repeatedly column chromatography was performed for the isolation and purification. The structures were elucidated on the basis of extensive spectral data (IR, MS, 1D- and 2D-NMR) analysis by comparing with literature data. A new cembranoid diterpene namely sarcophyolide A (1), together with 7α, 8β-dihydroxydeepoxysarcophine (2) were isolated from this species. The cembranoid diterpenes with γ-lactone could be chemotaxonomic markers of Sarcophyton sp.
