| Extraction Method | Solvent Extraction | Solvent Extraction | SFE | SFE | UAE | MAE |
|---|---|---|---|---|---|---|
| Solvent | MeOH (1:50 w/v) | MeOH (1:50 w/v) | CO2 and EtOH (3%, v/v) | CO2 | Deionized H2O (1:100 w/v) | EtOH (15:1 w/v) |
| Pretreatment | Wash, salted, boiled, blanched, cured | Avoid sunlight | Freeze dry | Milling and microwave assisted cell disruption | NA | NA |
| Extraction condition | 1 h, RT | 1 h, RT | 50 bar, 200 °C, 1 h | 40 bar, 400 °C, 3 h | 800 W, 80% amplitude, 20 kHz, 30 °C, 3 h. | ratios, 60 °C, 10 min, 300 W |
| Yield | 2.08 ± 0.04 mg/g | 4.96 ± 0.4 mg/g | 0.00753 μg/g | 38.5 mg/g | 0.031 mg/g | 2.12 mg/100 g |
