Isolation and Characterization of a Human Intestinal Bacterium, Eubacterium sp. ARC-2, Capable of Demethylating Arctigenin, in the Essential Metabolic Process to Enterolactone

Abstract excerpt

Plant lignans, such as pinoresinol diglucoside, secoisolariciresinol diglucoside and arctiin, are metabolized to mammalian lignans, enterolactone or enterodiol, by human intestinal bacteria. Their metabolic processes include deglucosylation, ring cleavage, demethylation, dehydroxylation and oxidation. Here we isolated an intestinal bacterium capable of demethylating arctigenin, an aglycone of arctiin, to...
