Total Phenolic Content and Radical Scavenging Potential of Celery Root and Celeriac Stalk and Leaf Extracts
Year: 2024
Type: article
Abstract: 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.
