Alginates have been extracted from seven brown algae found in the Southern Hemisphere and characterized by ~H and 13C NMR analyses. The results are compared with similar analyses obtained in this work for three commercially available alginates isolated from Macrocystis pyrifera, a species of the Nor

Methylation analysis of a fucose-containing, sulfated polysaccharide (C-II), which was isolated from the brown seaweed Ecklonia kurome and has a potent anticoagulant activity, showed the presence of 3-O- and 3,4-O-disubstituted fucopyranosyl residues in addition to small proportions of nonreducing,
## Abstract Two new abietane derivatives were obtained by treatment of the diterpene taxodione with diazomethane. Their structures were determined by mass spectrometry and NMR studies, including oneβ and twoβdimensional experiments. Copyright Β© 2004 John Wiley & Sons, Ltd.
