Parameters of the ultraperformance convergence chromatography (UPC2) method for determination of Thymol (Thl) and Carvacrol (Cal) in Thymi herba.
| Standard | RT (min) | Calibration Curve | r | LOD (ng) | LOQ (ng) | Linear Range (ng) |
|---|---|---|---|---|---|---|
| Thymol | 2.109 | y = 602.02x | 0.9998 | 1.31 | 2.63 | 5.25–168.00 |
| Carvacrol | 2.263 | y = 606.05x + 224.73 | 0.9999 | 1.57 | 3.14 | 6.28–201.00 |
Calibration curve: y = mx + b, where y is the integrated peak area and x is the concentration in ng. RT, retention time; LOD, limit of detection; LOQ, limit of quantification.
