Abstract:

Extraction conditions of burdock polysaccharide (BPS) were optimized by conducting single factor experiments and the following orthogonal test, and modulation effects of BPS on normal intestinal microflora of ICR mice were studied. The optimum conditions were as that burdock were extracted with hot water at 80℃ with the ratio of solid-liquid 1:10 for 60 min and extracted twice. The amounts of Bifidobacterium and Lactobacillus in mice of BPS treated groups significantly increased as compared with those in the blank group (P< 0.05) , but the number of E.coli, Enterococcus was not significantly changed (P> 0.05).

Key words: burdock polysaccharide, extraction, mice, intestinal flora
