The objective of this study was to optimize the extraction conditions for phenolic compounds, total flavonoids, and antioxidant activity from DegletNour variety. The extraction of active components from natural sources depends on different factors. The knowledge of the effects of different extraction parameters is useful for the optimization of the process, as well for the ability to predict the extraction yield. The effects of extraction variables, namely types of solvent (methanol, ethanol and acetone) and extraction time (1h, 6h, 12h and 24h) on phenolics extraction yield were evaluated. It has been shown that the time of extraction and types of solvent have a statistically significant influence on the extraction of phenolic compounds from DegletNour variety. The optimised conditions yielded values of 80.19 ± 6.37 mg GAE100 g FW for TPC, 2.34 ± 0.27 mg QE100 g FW for TFC and 90.20 ± 1.29 for antioxidant activity were methanol solvent and 6 hours of time. According to the results obtained in this study, DegletNour variety can be considered as a natural source of phenolic compounds with good antioxidant capacity.
