A novel sulfated glycosphingolipid, SGL-1, was isolated from the ascidian Ciona intestinalis, prepared from chloroform/methanol extracts and fractionated successively on DEAE Sephadex-A25, Florisil and Iatrobeads column chromatographies. Chemical structural analysis was performed using methylation analysis, gas-liquid chromatography, combined gas-liquid chromatography-mass spectrometry, matrix-assisted laser desorption/ionization time-of-flight mass spectrometry and 1H-NMR spectroscopy. This chemical structure is presented as GlcCer I6-Sulfate. The ceramide moiety was specified by t16:0, t17:0, br,t17:0, t18:0 and br,t18:0 as sphingoids, and 2-hydroxy, saturated fatty acids as represented by docosanoic and tetracosanoic acids.
