对南海软珊瑚Sarcophyton sp.中的西松烷二萜类成份进行研究,从发现具有新颖结构的次生代谢产物。采用多种色谱手段进行分离纯化,通过理化性质和光谱分析确定化合物结构。分离得到1个新的西松烷二萜类化合物,命名为Sarcophyolide A(1),和一个已知西松烷二萜类化合物7α,8β-dihydroxydeepoxysarcophine(2)。利用现代波谱确定新化合物的结构。
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, 1 D- and 2D-NMR) analysis by comparing with literature data. A new cembranoid diterpene namely sarcophyolide A (1), together with 7a, 8β-dihydroxydeepoxysarcophine (2) were isolated from this species. The cembranoid diterpenes with 7-1actone could be chemotaxonomic markers of Sarcophyton sp.
