Abstract:
Soft corals of the genus Sinularia are widely distributed in the South China Sea. Two new lipid analogues (Z)-N-(3,4-dihydroxyphenethyl)-3-methyldo-dec-2-enamide (1) and (E)-1-(2,5-dihydroxy-4-methylphenyl)-6-acetoxy-2,3,7-trihydroxy-3,7,11,15-tetramethylhexadeca-11,14-dien (2), together with three known compounds (3-5) were isolated from the soft coral Sinularia flexibilis. Their structures were elucidated on the basis of extensive spectroscopic analysis, including one and two-dimensional NMR, MS, IR, UV, as well as by comparison with published data.
