Abstract
A specimen of the marine sponge Agelas longissima was analyzed for glycosphingolipids. Three cerebrosides 1a‐3a were isolated, each as a mixture of homologs. The structure of the new glycosphingolipid 1a was elucidated by extensive NMR studies of its peracetate derivative and chemical analysis. Compound 2a, previously isolated from another specimen of A. longissima, exhibits in the new specimen a remarkably different alkyl chain composition.Keywords
