(A) CAA graph of rice extracts at 1 mg/mL. (B) Rice extracts at 0.5–5 mg/mL inhibited peroxyl radical-induced DCFH oxidation to DCF and ROS production in Caco-2 cells. Using one-way ANOVA, the data were reported as means ± standard deviations (n = 3). Tukey’s test at p < 0.05 shows significant differences between the columns using different alphabets (a–d). Note: (DCFH: 2’,7’–dichlorofluorescein diacetate, DCF: 2’, 7’–dichlorofluorescein, ROS: Reactive oxygen species, CAA- Cell antioxidant assay).
