Antioxidant activity of the essential oils in the maximum concentration tested using the DPPH and ABTS assays.
| Essential Oil (Highest Concentration Used) | % DPPH Inhibition | % ABTS Inhibition | ABTS (μmolesEA/g) * |
|---|---|---|---|
| Kumquat (43 mg/mL) | 34.5 ± 0.07 | 6.7 ± 0.1 | 326.2 ± 0.05 |
| Spearmint (4.8 mg/mL) | 6 ± 1.45 | 53.2 ± 0.02 | 9833.3 ± 10.5 |
| Basil (49 mg/mL) | 14.5 ± 0.01 | 43.7 ± 0.03 | 834.3 ± 3.4 |
| Anise (48.5 mg/mL) | 48 ± 0.07 | 18.6 ± 0.03 | 383.5 ± 6 |
| Ascorbic acid (0.11 mg/mL) | 76.5 ± 0.002 | 96.5 ± 0.001 | - |
Representative results from at least three independent experiments; * micromoles ascorbic acid equivalent per gram of essential oil.
