Studies on the Natural Products of the Formosan Soft Coral Sinularia sp.
Abstract (Summary)The chemical constituents of EtOH extracts of the soft coral Sinularia sp. have led to the isolation of nature compounds¡]1-12¡^,sinularioperoxides A-D¡]1-4¡^, sinulariolins A-D¡]5-8¡^, 1a,3b-Dihydroxy-24-methylencholesta-5,9-diene¡]9¡^,¡]3S¡^-3,7-Dimethyl-nona- 6,8-dienoicacid¡]10¡^, ¡]2¢S¡^-Ethyl¡]5¢E¡^-5-(2¢,6¢-dimethylocta-5¢,7¢-dienyl)furan-3-carboxylate¡]11¡^, and one know metabolite, 3'R,4'-((2R, 4S)-2-hydroxy-4-acetoxy-2,6,6-trimethyl-cyclohexylidene)but-3'-en-2'-one¡]12¡^, respectively. Compounds 1-11 are new and 12 is a know metabolite, which had been isolated from the brown alga and the plant. The structures of 1-12 were elucidated by the interpretation of spectroscopic data¡]UV, MS, IR, 1D and 2D NMR¡^.
