The aim of the present study was the optimization of the extraction conditions (particle size, solid-to-solvent ratio, extraction time and procedure) via total polyphenol content and radical scavenging activity, using wild thyme as a natural source of polyphenols. According to the total polyphenols yield, particle size, solvent-to-solid ratio and e...

Various conventional (maceration and heat-assisted extraction) and new alternative techniques (ultrasound-assisted extraction and microwave-assisted extraction) have been developed for the extraction of polyphenols compounds from different plant sources. Novel procedures have established with the aim to reduce the extraction time and solvent consum...
