Trapping of MGO by (A) EGC (3), (B) EGCG (2), and (C) quercetin (1). MGO was incubated with the test flavonoids (0.25, 0.5, 1.5, and 2.5 mM) in pH 7.4 phosphate buffer solutions at 37 °C for 10, 30, 60, 120, and 240 min. The remaining MGO was reacted with DB to give methylquinoxaline which was quantified by HPLC. Each value represents the mean ± SD (n = 3)
