- TEAC: Trolox equivalent antioxidant capacity
- Significant difference obtained with: *P < 0.05; **P < 0.01; ***P < 0.001
- The reported comparisons concern: Seeds aqueous extract versus roots aqueous extract, leaves aqueous extract versus roots aqueous extract and control(a) versus roots aqueous extract. Every concentration is compared with its equivalent in the other extract.
