Abstract
Polysaccharides were extracted from Broussonetia papyrifera ((L.) L’Herit. ex Vent.) fruits (BPP), and response surface methodology was used to maximize extraction yield. The optimum extraction conditions were: ratio of water to solid, 30mL/g; extraction duration, 50min; extraction power, 180W; and extraction temperature, 60°C. Under these conditions, the yield of BPP was 8.61%. Then, BPP was purified, and three purified fractions (designated BPP-1, BPP-2 and BPP-3) were obtained for further physicochemical properties, antioxidant activity and antibacterial activity analysis. These fractions were mainly composed of glucose, mannose and arabinose residue, meanwhile, BPP-3 had a significantly higher rhamnose and uronic acid content than BPP-1 and BPP-2. And BPP-3 showed the best hydroxyl radial scavenging activity, ferric reducing activity power (FRAP), antihemolytic activity and antibacterial activity.
