ABSTRACT
<p><b>AIM</b>To study the chemical structure of SC3, an acidic polysaccharide from Salvia chinesis.</p><p><b>METHODS</b>Based on chemical (including sugar composition analysis, methylation analysis, uronic acid reduction and partial acid hydrolysis) and spectral analysis (IR, NMR, ESI-MS), the structural characterization of SC3 was investigated.</p><p><b>RESULTS</b>SC3 was composed Rha, Ara, Gal and GalA, with its mean molecular weight of 7.7 x 10(4). By means of methylation analysis, partial acid hydrolysis, NMR and ESI-MS spectrum, the linkages and sequence information of SC3 were obtained.</p><p><b>CONCLUSION</b>SC3 is an complicated acidic polysaccharide, obtained for the first time from the plant.</p>
