Comparison of traditional and modern extraction methods.

Method		Time	Solvent Usage	Cost	Instrument Cost	Sample Size	Efficiency	Polyphenols’ Yield
Traditional	Soxhlet extraction	Moderate	Moderate	Moderate	High	Large	Low	Low
	Maceration	Long	Large	Moderate	Low	Large	Low	Moderate
	Percolation	Moderate	Moderate	Moderate	Low	Large	Moderate	Moderate
Modern	UAE	Short	Little	Low	Low	<30 g	High	High
	MAE	Short	Little	Moderate	High	<10 g	High	High
	SFE	Short	Little	High	High	<5 g	High	High

UAE, ultrasound-assisted extraction; MAE, microwave-assisted extraction; SFE, supercritical fluid extraction.
