Three novel arsenic-containing ribosides, methyl 5-deoxy-5-(dimethylarsinoyl)-β-D-riboside, 1-O-mannitol, and a dimethylarsonio-β-D-riboside have been isolated from extracts of the brown alga Sargassum lacerifolium.In addition, five previously reported arsenic-containing ribosides, and some arsenate, were isolated from Sargassum, and dimethylarsinic acid was also shown to be present.The compounds were identified chiefly by NMR spectroscopy, and an X-ray molecular structure is reported for one of them, 2-amino-3-propane-1-sulphonic acid.The stereochemistry of the aglycones in these arsenic-containing ribosides is discussed and the configuration of 3--2-hydroxypropane-1-sulphonic acid 4 was assigned as 2S on the basis of a comparison of NMR spectra with those of synthetic model compounds.
