Observed and predicted levels for optimal extraction conditions.
| Factor | Optimal Level | ||
|---|---|---|---|
| X1 (W) | 375 | ||
| X2 (°C) | 109 | ||
| X3 (min) | 30 | ||
| Response | Predicted (μg/g) | Experimental (μg/g, n = 3) | Residual (%) |
| THC (μg/g) | 2.38 | 2.47 ± 0.28 | 3.8% |
| CBD (μg/g) | 2.49 | 2.56 ± 0.17 | 2.8% |
| CBN (μg/g) | 0.97 | 1.06 ± 0.16 | 9.3% |
Residual (%) = (observed value − expected value)/expected value × 100%. X1: microwave power, X2: temperature, X3: extraction time. THC: Δ9-tetrahydrocannabinol, CBD: cannabidiol, CBN: cannabinol.
