Total flavonoid levels A, superoxide dismutase (SOD) levels B, peroxidase (POD) levels C, catalase (CAT) levels D, and 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity E of A. rugosa under different ozonated water treatments (0, 1, 10, 20, 40, and 80 s at 1 µmol mol−1). Each value indicates the mean ± SE of three samples (n = 3). Different letters represent the significant differences at p ≤ 0.05, as assessed using ANOVA, followed by Tukey’s multiple range test
