Abstract: In this study, theabrownin (Mw>50 kDa, TB) extracted from pu-erh tea was used as experimental material, and the effects of theabrownin to the intestinal flora of rat was studied. The results showed that the theabrownin had remarkable effects on the intestinal flora in rats. TB could significantly improve the de-pollution of antibiotics and adjust the intestinal flora imbalance. It was found that TB could promote the proliferation of Bifidobacterium and Lactobacillus and inhibit the proliferation of Escherichia coli and Enterococcus. The effects are more obvious with increasing culture time. In turn, microbes proliferate can accelerate the catabolism of theabrowns.
