Furanoterpene fatty acid esters from the Australian marine sponge Coscinoderma mathewsi

Abstract

Chemical investigation of the sponge Coscinoderma mathewsi collected near Mooloolaba, S.E. Queensland, has led to the isolation of the furanoterpene esters 1a - 1c together with the known furanoterpenes 2 - 4. NMR spectroscopic assignments are provided for the esters, while GC/MS analysis of FAME derivatives 5a - 5c confirmed the identity of the fatty acid components. ©ARKAT-USA, Inc.
