摘要：

From the dichloromethane extract of the brown alga Dilophus mediterraneus nine diterpenes, belonging to different skeletal classes, were isolated and characterised spectroscopically (MS, NMR, UV and IR). The structure of a new natural diterpene (IR*, 2E, 4R*, 7E, 11R*, 12S*)- 12, 18-dihydroxydolabella-2,7-diene) was resolved with the aid of the lanthanide shift reagent Europium(III)-tris(1,1,1,2,2,3,3)-heptafluoro-7,7-dimethyl-d6-octa-4,6-dion-d3, C30H3D27EuF21O6, (Eu(fod)3).
