o:35756 Total Phenolic Content and Radical Scavenging Potential of Celery Root and Celeriac Stalk and Leaf Extracts en 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 leaf sample>water celeriac leaf sample>ethanol celeriac stalk sample>water celery root sample. Ethanol celery root and water celeriac stalk samples showed significantly lower TPC. The anti-DPPH activity follows the trend: ethanol celeriac leaf sample>water celeriac leaf sample>water celery root sample>water and ethanol celeriac stalk samples>ethanol celery root sample. The IC50 values (the concentration of the sample necessary to neutralize 50% of free radicals) varied in a range of 63.9 to 326.4 mg/mL. Both phenolic yield and antioxidant activity achieved the highest levels in the ethanol celeriac leaf sample. celeriac leaf, celeriac stalk, celery root, extraction, polyphenols, radical scavenging activity 1552099 https://doi.org/10.61652/leksir2444004P 2025-01-24T12:11:36.312Z 44 yes 46 Ana Plećić University of Belgrade, Institute for the Application of Nuclear Energy, Serbia 0000-0002-3160-3598 Marija Gnjatović University of Belgrade, Institute for the Application of Nuclear Energy INEP, Serbia doktor tehnoloških nauka person 0000-0001-8233-1636 Aleksandra A.
