In recent years, the effect of tea on intestinal microflora attracted widespread attention. In this study, the green tea infusion with human fecal was mixed, the change of intestinal flora related to obesity in different fermentation time points (0, 6, 12, 24 h) were measured and the role of tea regulated intestinal microflora was evaluated. The results showed that green tea infusion inhibited the reduction of total gut bacteria, Bacteroides and Firmicutes after fermentation for 24 h (P<0.05), improved the relative abundance of Bacteroides and Firmicutes, reduced the F/B ratio, which provides a reference to support the important role of green tea infusion in improving intestinal health, reducing weight and lowering blood lipid.
