RESEARCH SUMMARY: Quercetin
KEY FINDINGS:
Optimization of Quercetin Extraction
- The study optimized sequential microwave-ultrasound-assisted extraction to maximize quercetin and total flavonoid yields from red onion skin wastes.
- Optimal conditions included 60 seconds of microwave irradiation followed by 15 minutes of sonication at 70°C, using 70% ethanol with a solvent-to-solid ratio of 30 mL/g.
- Under these conditions, the maximum recovery yields were 10.32% for quercetin and 12.52% for total flavonoids.
