Altenzymes present in the colonic microbiota catalyze along the intestinal absorption of flavohough phase II conjugation reactions take place not just the degradation of some flavonoid aglycones by way of C-ring cleavage, demethylation and/or dehydroxylation reactions, but noids have an effect on, in general, the bioavailability of their aglycones, some studies have pointed also that at many flavonoid glycosides, through O-deglycosylation and ester hydrolysis, and out that, of least f
