Figure 3

Antioxidant activity (DPPH free-radical-scavenging assay) (A) illustrating WB; (B) illustrating OB of the extracts (control and fermented (6 days)). The percentage inhibition (I%) was calculated as [1 − (test sample absorbance/blank sample absorbance)] × 100. Values are expressed as mean values ± SD, I%, n = 3, and are followed by different letters (a–f) indicating significant differences (p < 0.05) between days of fermentation (One-way ANOVA - Multiple comparison test -Tukey multiple range test (p = 0.05)-GraphPad Prism Version 8.0.1, Graph Pad Software, Inc., San Diego, CA, USA).
