  • Publication number: 20220257559
    Abstract: Proposed is an intestinal microbiome-improving composition containing ellagic acid as an active ingredient. The ellagic acid inhibits the growth of harmful bacteria such as Verrucomicrobia and Bacteroidetes attributable to alcohol intake and increases the growth of beneficial bacteria such as Firmicutes, thereby controlling intestinal microbes. As a result, the ellagic acid exhibits the effect of inhibiting an increase in a plasma endotoxin level, an increase in an intestinal TNF-? level, an increase in intestinal oxidative stress, a decrease in expression of intestinal TJ and AJ proteins, liver fat accumulation, an increase in plasma ALT, an increase in triglycerides, and hepatic oxidative stress and apoptosis. The composition containing ellagic acid as an active ingredient is provided as an intestinal microbe-improving composition and a preventive and therapeutic preparation for alcoholic fatty liver.
