|---|---|---|---|---|---|---|---|---|
| Oleuropein | 0.037 | 0.136 | y = (1.15 ± 0.21) + (2.00 ± 0.06) | 0.992 | 5.2 | 6.2 | 89.7 | −15.4 |
| Tyrosol | 0.045 | 0.098 | y = (0.01 ± 0.02) + (1.18 ± 0.01) | 0.999 | 4.6 | 5.8 | 92.5 | −11.1 |
| Hydroxytyrosol | 0.048 | 0.096 | y = (0.13 ± 0.05) + (0.53 ± 0.02) | 0.993 | 3.8 | 5.1 | 91.4 | −12.8 |
LOD: limit of detection, LOQ: limit of quantification, r2: regression coefficient, RSD: relative standard deviation, RE: recovery, ME: matrix effect.
