Triacylglycerols, Fucosterol, Diacylglyceroglycolipids and Fucoxanthin from Fucus virsoides J. AG.

Abstract

From the marine brown macroalga Fucus virsoides J. AG. (Fucales, Phaeophyceae), a mixture of triacylglycerols 1-3, fucosterol 4, a mixture of galactosyldiacylglycerols 5-8 and fucoxanthin 9 have been isolated. Normal phase column flash chromatography was effective for the isolation of the marine compounds. FAB-MS. CI-MS spectrometry, 1H NMR, 13C NMR, 1H-1H COSY and 1H-13C COSY experiments were useful in providing informations for their structure elucidation. © 1994 Verlag der Zeitschrift für Naturforschung.
