Total Phenolic Content and Radical Scavenging Potential of Celery Root and Celeriac Stalk and Leaf Extracts
In the study, celery root and celeriac stalk and leaf extracts were prepared using heat-assisted extraction, and the total polyphenol concentration (TPC) and anti-DPPH radical potential of the obtained extracts were determined. The TPC values of the extracts were from 2.67 to 13.43 mg gallic acid equivalent/g, following the trend: ethanol celeriac ...

Natural deep eutectic solvent as tool for improving Rosa canina L. polyphenol recovery in maceration
Rosa canina L. extracts were prepared using water or three natural deep eutectic solvents (NADESs: betaine+malic acid, betaine+sucrose, and citric acid+sucrose with 50% of water) and maceration. The extracts were characterized in terms of total polyphenol content (TPC), ABTS radical scavenging potential, extraction yield, zeta potential, conductivi...
