In the present study, bee pollen polysaccharides from Rosa rugosa (WRPP) were extracted and fractionated. WRPP were purified to neutral (WRPP-N) and acidic polysaccharides (WRPP-1, WRPP-2) with DEAE-Cellulose. WRPP-N were mainly composed of glucose, mannose, arabinose and galactose, indicating the existence of glucan, arabinogalactan (AG) and mannoglucan. WRPP-1 mainly consisted of rhamnose (3.0%), galacturonic acid (12.4%), galactose (24.7%) and arabinose (53.9%), and contained a large…
