Overview

Ultrasound-assisted extraction improves flavonoid yield in Cercis chinensis seeds, suggesting NADES as an eco-friendly method.

Key Points

  • Total flavonoid yield reached 128.5 mg/g using optimized ultrasound-assisted extraction parameters.
  • Choline chloride–levulinic acid exhibited the best performance, yielding 112.1 mg/g flavonoids.
  • Extraction kinetics showed a temperature dependence, emphasizing the impact on efficiency.
  • The extracted flavonoids demonstrated significant antioxidant activity with IC50 values of 0.86 mg/mL and 0.69 mg/mL.
