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

Figure 7

Effect of extraction time on the extraction content of resveratrol from peanut roots. UAE conditions: solid/liquid ratio of 1 : 30 (g/mL), 60°C, ultrasonic power of 40 kHz, extraction solvent of choline chloride/1,4-butanediol (DES-1), choline chloride/1,4-butanediol molar ratio of 1 : 3, and 30% of water (v/v).
