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

Table 2

It is shown the corresponding concentration of polyphenols in the tested volume expressed in μg/μL. The calibration curve was constructed employing dependence between peak areas and concentration, using the mean values of three determinations for each concentration.
