[Abstract]
Object To study the polysaccharides from Salvia chinensis Benth. Methods DEAE-cellulose and gel-filtration chromatography were used to isolate and purify the polysaccharides whose structures were characterized by using chemical and spectral Methods. Results Two homogeneous polysaccharides,named SC5 and SC6,were obtained from the water and diluted-alkaline extract,respectively,with their molecular weights estimated by HPGPC to be 4.8×104 and more than 1.0×106. Both structures were investigated to be complicated acidic polysaccharides. Conclusion The two polysaccharides are obtained for the first time from this plant.
