Antioxidant activity of Pistacia lentiscus seed oil (PLSO).
| IC50 Values (mg/mL) | (Trolox Equivalent) | |||
|---|---|---|---|---|
| Samples | DPPH | FRAP | Iron Chelating (FIC) | KRL |
| PLSO | 5.010 ± 0.095 | 1.15 ± 0.23 | 5.61 ± 0.14 | 4440.00 ± 493.60 |
| AO | − | − | − | 360.80 ± 153.60 |
| EDTA (standard) | − | − | 0.60 ± 0.09 | − |
| AA (standard) | 0.810 ± 0.270 | 0.41 ± 0.16 | − | − |
| α-tocopherol | − | − | − | 0.94 ± 0.01 |
Each value represents the mean of three determinations ± standard deviation. IC50: half-maximal inhibitory concentration; PLSO: Pistacia lentiscus L. seed oil; AO: argan oil, EDTA: ethylenediaminetetraacetic acid; AA: ascorbic acid; DPPH: 2,2-diphenyl-1-picrylhydrazyl; FIC: Ferrous Iron Chelating FRAP: Ferric Reducing Antioxidant Power; KRL: Kit Radicaux Libres. For the KRL test, data are presented in Trolox equivalent: 1 mL of PLSO is equivalent to X moles of Trolox (value shown in the table).
