Ultrasound-Assisted Simultaneous and Efficient Extraction of Flavonoids and Polysaccharides from Hawthorn ( Crataegus pinnatifida ): Optimization and Bioactivity
Given the challenges in co-extracting flavonoids and polysaccharides from hawthorn (Crataegus pinnatifida), this study developed a green approach using ultrasound-assisted deep eutectic solvents. Among eleven choline chloride-based DES systems screened, choline chloride-ethylene glycol exhibited the best co-extractio...
