Antioxidant Effect of Beer Polyphenols and Their Bioavailability in Dental-Derived Stem Cells (D-dSCs) and Human Intestinal Epithelial Lines (Caco-2) Cells

Figure 5

Bioavailability of beer polyphenols in the Caco-2 cell model. Cells were treated with beer fractions: must (must), prehopping solution (pre-h), and posthopping solution (post-h), for 4 h. The bioavailability of individual polyphenols in beer extracts is expressed as % of polyphenols which exceeds the apical compartment and passes into the basolateral compartment and collected for HPLC analysis.
