  • Title: The agminosides: naturally acetylated glycolipids from the New Zealand marine sponge Raspailia agminata.
    Author: Wojnar JM, Northcote PT.
    Journal: J Nat Prod; 2011 Jan 28; 74(1):69-73. PubMed ID: 21087018.
    Abstract:
    Examination of the New Zealand sponge Raspailia agminata resulted in the isolation of five members of a novel family of glycolipids, agminosides A-E (1-5). These large and complex molecules contain up to six partially acetylated glucose residues. The chromatographic separation of these compounds was a challenge due to the similarity of the congeners and their lack of a chromophore. MS-guided isolation followed by extensive NMR analysis and chemical derivatization eventually led to the purification and identification of 1-5.
