摘要：

Digeneaside (alpha-D-mannopyranosyl-(1 -> 2)-D-glycerate) was extracted from the red algae, Bostrychia binderii, and purified by adsorption and gel-filtration chromatography. HPLC and ESIMS techniques were used to follow purification steps and characterize digeneaside. NMR spectroscopy experiments (1D H-1, C-13, DEPT and 2D HMQC, COSY and TOCSY) were used to fully assign the H-1 and C-13 spectra. (c) 2006 Elsevier Ltd. All rights reserved.
