摘要

A novel briarane-type diterpenoid,fragilide A(1),has been isolated from the Taiwanese gorgonian coral Junceella fragilis.The structure,including the relative configuration of this new metabolite,was elucidated by spectroscopic methods.In connection with our long-standing interest in the chemistry of marine invertebrates,we investigated the Indo-Pacific gorgonian corals collected off the Southern coast of Taiwan.From one of the gorgonian corals,Junceella fragilis(Cnidaria,Gorgonacea,Ellisellidae),we isolated a novel briarane-relat-ed derivative 1,designated as fragilide A.The gorgonians of the genus Junceella are well-known for containing briarane-type metabolites.The freshly collected gorgonian coral was kept frozen until needed.Fragilide A(1)was obtained from the ethyl acetate extract,after chromatography on silica gel,as a white powder.
