DPPH scavenging assay was used for measuring the antioxidant activities of the synthesized nanoparticles at 517 nm using DPPH solution under the conditions described in Materials and Methods. Calculated mean is for triplicate measurements from three independent experiments ± SD, ^a − hMeans with different superscripts in the same column are considered statistically different (LSD test, P ≤ 0.05)
