Green and Efficient Extraction of Resveratrol from Peanut Roots Using Deep Eutectic Solvents

Figure 3

Effect of choline chloride/1,4-butanediol molar ratio on the extraction content of resveratrol from peanut roots. UAE conditions: solid/liquid ratio of 1: 20 (g/mL), 25°C, 30 min, ultrasonic power of 40 kHz, extraction solvent of choline chloride/1,4-butanediol (DES-1), and 20% of water (v/v).
