Triacylglycerols, Fucosterol, Diacylglyceroglycolipids and Fucoxanthin from Fucus virsoides

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, 1 H NMR, 13 C NMR, 1 H- 1 H COSY and 1 H- 13 C COSY experiments were useful in providing informations for their structure elucidation
