The aim of the study was to examine the antioxidant activities and determine the phenolic profile of Deglet-Nour roasted date pit extracts. Significant variations were observed in the total phenol content, which amounted to 1.318±0.0008 mg EAG/g dry extract, as well as in the total amount of flavonoids, measured at 77.14±11.7 mg EQ/g extract. DPPH free radical scavenging activity and FRAP iron reduction capacity were also assessed, with remarkable results of 0.82 mg/ml and 6.36 mg/g respectively. These results highlight the potential of roasted date pits as a food alternative and natural resource, thanks to the presence of several important compounds with phenolic properties and high antioxidant capacity. In conclusion, the analyses carried out support the idea that the consumption of roasted date stone powder is recommended and encouraged due to its many health benefits.frRoasted date pits - polyphenols - antioxidant activity - DPPH -FRAP - flavonoidsThesis
