Table 3.
IC50 values of melanoma cells A375 treated with the essential oils after 72 h.
| Treatments | A375 Cells |
|---|---|
| Essential Oils | IC50 a (µg/mL) |
| F1 | 21.1 ± 0.17 |
| L1 | 23.4 ± 0.15 |
| F2 | 15.3 ± 0.13 |
| L2 | 16.2 ± 0.17 |
| F3 | 16.3 ± 0.14 |
| L3 | 19.7 ± 0.18 |
| F4 | 6.7 ± 0.22 |
| L4 | 4.5 ± 0.18 |
a Results are expressed as IC50 values (mg/mL) ± SD. The IC50 value, relative to untreated control, represents the concentration that inhibited cell vitality by 50%. Each value represents the mean ± SD of three experiments, performed in quadruplicate.
