Antioxidant capacity measured by FRAP, ABTS·+ and DPPH· radical assays for phloridzin (PZ) and myristic acid ester of phloridzin (PZM).
| Compound | FRAP (μmol AE L−1) | ABTS (μmol AE L−1) | DPPH (μmol AE L−1) |
|---|---|---|---|
| Phloridzin | 77.9 ± 5.17 | 1794 ± 20.7 | 3.99 ± 0.3 |
| PZM | 95.9 ± 3.77* | 1792 ± 85.1 | 1.76 ± 0.003** |
Results were expressed as Means ± SD, *P˂0.05, **P˂0.01.
Antioxidant activity unit: μmol ascorbic acid equivalents/L of 1 mM of solution; PZM: Phloridzin myristate.
