| Assay | Ascorbic acid∗ | Trolox∗ | S. officinalis EO | M. suaveolens EO |
|---|---|---|---|---|
| DPPH | 10.73 ± 0.82 | 17.42 ± 1.85 | 93.67 ± 2.17a,b,c | 53.19 ± 1.12a,b |
| ABTS | 36.29 ± 1.74 | 35.64 ± 3.27 | 129.74 ± 2.11a,b,c | 75.19 ± 1.80a,b |
| FRAP | 18.95 ± 1.56 | 39.16 ± 2.14 | 112.41 ± 3.18a,b,c | 69.48 ± 2.05a,b |
DPPH, 2,2′-diphenyl-1-picrylhydrazyl radical scavenging assay; ABTS, 2,2-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid radical scavenging assay; FRAP, Fe+3 reducing/antioxidant power assay. ∗Ascorbic acid and Trolox were used as antioxidant positive controls. Values are IC50 in μg/mL and a,b,cp < 0.05 vs. ascorbic acid, Trolox, and M. suaveolens EO, respectively.
