TLDR The best method to extract quercetin from these leaves is using a specific ionic liquid with salt, which is more efficient and uses fewer solvents.
The study aimed to optimize the extraction of quercetin from Nothopanax scutellarium leaves using ionic liquid-based microwave-assisted extraction. Among the tested ionic liquids, 1-butyl-3-methylimidazolium tetrafluoroborate combined with sodium chloride was found to be the most effective, yielding the highest quercetin content of 26.13 mg/g. This method improved upon conventional extraction techniques by reducing the need for large volumes of organic solvents and long extraction times, offering a more efficient approach to obtaining quercetin from these leaves.
