| Correlation (R) | ||||
|---|---|---|---|---|
| TPC | TFC | TPrC | TTC | |
| ABTS radical | 0.500 | 0.866 | 0.861 | 0.640 |
| DPPH radical | 0.929∗ | -0.370 | 0.361 | 0.979∗ |
| H2O2 radical | -1.00 | -0.002 | 0.011 | -0.985∗ |
| NO radical | 0.975∗ | 0.223 | -0.214 | 0.999∗ |
TPC: total phenolic content; TFC: total flavonoid content; TPrC: total proanthocyanidin content; TTC: total terpenoid content. The coefficient values with asterisks indicate significant difference at p ≤ 0.05.
