The potential prebiotic properties of Panax ginseng polysaccharides were studied using ten strains of Lactobacillus plantarum isolated from traditional Chinese fermented foods. These probiotics showed different growth characteristics depending on the extract and strain specificity. L.plantarum C88 showed higher cell densities and growth rate when cultured on P.ginseng polysaccharides. In the invitro antioxidant assay, P.ginseng polysaccharides combined with L.plantarum C88 were found to possess significant DPPH, ABTS and superoxide anion radicals scavenging activities, and acidic polysaccharides showed better antioxidant activity than neutral polysaccharides. Furthermore, we evaluated the antioxidant effect of acidic P.ginseng polysaccharide combined with L.plantarum C88 strain in natural ageing mice invivo. Acidic P.ginseng polysaccharide and L.plantarum C88 together inhibited the formation of malondialdehyde (MDA) and increased the activities of superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), catalase (CAT) and total antioxidant capacities (T-AOC) in a dose-dependent manner.
