| Abstract: | Methyl sartortuoate was first obtained from soft coral Sarcophyton sartortuosum and its struc- ture was determined mainly by X-ray single crystal diffraction analysis. In our continuing study on the bio- active substances of soft coral, three more new tetraterpenoids and a known compound, methyl sartortuoate, were isolated from the same species of soft coral. The structure of methyl sartortuoate has been elucidated by means of 1D and 2D NMR techniques. At the same time, 1H and 13C NMR signals have been assigned definitely. This information was very useful for the structural determination of the tetraterpeneoids with this skeleton. |
