摘要：The extraction parameters of water-soluble polysaccharides (WPs) from whitehyacinth bean were optimized using single-factor and orthogonal experiment. Theantioxidant activities of WPs were presented by assaying three different radicals,2,2-diphenyl-1-picrylhydrazy radical (DPPH radical), hydroxyl radical andsuperoxide radical scavenging ability. In addition, the effects of WPs obtained onthe growth of three probiotic strains (Lactobacillus acidophilus LA5,Bifidobacterium bifidum BB01 and Lactobacillus bulgaricus LB6) were alsodetermined by measuring the OD and pH value of culture medium. According tothe results, the optimum extraction parameters were as follows: the ratio of waterto material was 50, extraction time was 2h and the extraction temperature was 95°C.The yield of WPs reached 1.15±0.07% under this condition. In addition, the WPshad different scavenging ability on three radicals (hydroxyl > DPPH > superoxide).And the WPs could promote the growth of LA5, BB01 and LB6.
