Two furanosesquiterpenes, (5¡¯E)-5-(2¡¯,6¡¯-dimethylocta-5¡¯,7¡¯-dienyl) furan-3-carboxylic acid (1) and (1¡¯E,5¡¯E)-5-(2¡¯,6¡¯-dimethylocta-l¡¯,5¡¯,7¡¯-trienyl) furan-3-carboxylic acid (2), were isolated from soft coral Sinularia lochmodes collected from Palikir pass at Pohnpei Micronesia, June, 1990 in Hawaii. Their structures were elucidated by 1H, 13C NMR, Homo-COSY, 1H-13C (1 bond) Heteronuclear Multiple Quantum Coherence Spectroscopy (HMQC), 1H-13C (2 and 3 bond) Heteronuclear Multiple Bond Coherence Spectroscopy (HMBC), Electron Impact Mass Spectroscopy (EI-ms), and Infrared Spectroscopy (IR).
