摘要：

Six new biscembranoids, namely, sarcophytolides G-L (1-6, resp.), together with six known analogs, were isolated from a marine soft coral Sarcophyton elegans. The structures of the new compounds were established on the basis of 1D- and 2D-NMR (COSY, HSQC, HMBC, and NOESY) spectroscopic analysis together with the aid of MS, CD, and IR data. The unusual isobiscembranoid sarcophytolide G (1) was found for the first time in the genus Sarcophyton.
