TRIACYLGLYCEROLS, FUCOSTEROL, DIACYLGLYCEROGLYCOLIPIDS AND FUCOXANTHIN FROM FUCUS-VIRSOIDES J AG

From the marine brown macroalga Fucus virsoides J. AG. (Fucales, Phaeo phyceae), a mixture of triacylglycerols 1-3, fucosterol 4, a mixture o f galactosyldiacylglycerols 5-8 and fucoxanthin 9 have been isolated. Normal phase column flash chromatography was effective for the isolati on of the marine compounds. FAB-MS, CI-MS spectrometry, H-1 NMR, C-13 NMR, H-1-H-1 COSY and H-1-C-13 COSY experiments were useful in providi ng informations for their structure elucidation.
