| Abstract: | Three guaiane-type sesquiterpenoids (1−3) and five steroids with 3β-hydroxy-5-en-7-one moiety (4−8) were obtained from gorgonian Echinogorgia sassapo reticulata collected from the South China Sea. Among them, new compound 1 was identified as (1S,5S,8S)-8-methoxy-menelloide B by spectroscopic methods including IR, HRESIMS, 1D and 2D NMR, and ECD spectra. All compounds except for 3 were obtained for the first time from the genus Echinogorgia. The chemotaxonomic significance of these compounds was summarized. |
