Antioxidant capacity of DHCA and QT according to different cell-free antioxidant assays.
| Samples | ABTS•+ (μM TE/μM) | DPPH•IC50 (μM) | XOD IC50 (μM) |
|---|---|---|---|
| DHCA | 5.09 ± 0.76 | 7.65 ± 0.08∗ | 0.96 ± 0.03∗ |
| QT | 6.26 ± 0.23 | 8.48 ± 0.15 | 0.35 ± 0.02 |
Results are expressed as mean ± SD (n = 3). ∗ in each column indicates a significant difference compared with QT according to Tukey tests (p < 0.05). IC50: inhibitory concentration to 50%; TE: trolox equivalent.
