Fig. 5From: Ozonated water soaking improves the flower growth, antioxidant activity, and bioactive compound accumulation in Agastache rugosaTotal 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 testBack to article page
