Overview

Kinetic modeling reveals improved polyphenol yield and antioxidant activity using ultrasound-assisted extraction, indicating its efficiency over conventional methods.

Key Points

  • Ultrasound-assisted extraction significantly enhances polyphenol yield, achieving 482 µg GAE/mg DM compared to 420 µg with maceration.
  • Flavonoid content increased to 14.18 µg QE/mg DM with ultrasound, outperforming 7.72 µg QE/mg DM achieved by maceration.
  • Antioxidant activity (FRAP) reached a saturation concentration of 238 µg Trolox/mg DM with ultrasound, indicating greater efficiency.
  • Kinetic modeling showed an excellent correlation (R2 > 0.99) across all conditions, underscoring the reliability of the results.
