Abstract
Four water-soluble arsenic compounds were isolated from the brown alga S. divaricata by a combination of chromatographic methods. They were all identified by mainly 1H NMR spectroscopy to be arsenic-containing ribofuranosides; 2,3-dihydroxypropyl 5-deoxy-5-(dimethylarsinoyl)-β-ribofuranoside (1a), 2-amino-3-[5-deoxy-5-(dimethylarsinoyl)-β-ribofuranosyloyl]propane-1-sulfonic acid (1b), 1 -‘glycerophosphoryr’-2-hydroxy-3-[5-deoxy-5-(dimethylarsinoyl)-β-ribofurano-syloxy]propane (1c), and 3-[5-deoxy-5-(dimethylarsinoyl)-β-ribofuranosyloxy]-2-hydroxypropane-1-sulfonic acid (1d). These compounds (1a~d) accounted for 75% of the arsenic in the algal extract.
