Antioxidant activity of new compounds 1–3. (A) Hydroxyl radical scavenging and (B) SOD activity of new compounds 1–3. All the data were confirmed by technical replicated (n = 3). The results are presented as the mean ± SD. Values with different letters (a, b, c, d, e) are significantly different one from another (one-way ANOVA followed by Newman–Keuls multiple range test, p < 0.05).
