The aim of this study was the investigation of the total phenolic content, flavonoid, and the assessment of the antioxidant potential of Cichorium intybus L. flowers grown in the Kosovo region. The flowers of Cichorium intybus L. were collected, dried, and extracted with solvents with different polarities (water, EtOH, MeOH, EtOAc, and acetone), using the extraction method. The total phenolic and flavonoid contents were analyzed by using Folin-Ciocalteu's and AlCl3 reagents, respectively. The antioxidant activity was assessed by DPPH in vitro assay methods. The obtained results revealed variation in the content of phenolic compounds (5.2 mg GAE/gDW in water extract, 6.8 mg GAE/gDW in ethanolic extract,72.1 0.3 mg GAE/gDW in methanolic extract, 45.3 0.1 mg GAE/g DW in ethyl acetate extract,and 31.3 0.1 mg GAE/gDW in acetone extract), flavonoid (2.9 mg CE/gDW in water extract, 19.0 mg CE/gDW in ethanolic extract,30.50 mg CE/gDW in methanolic extract, 27.1 mg CE/gDW in ethyl acetate extract, and 25.4 mg CE/gDW in acetone extract), and antioxidant activity (23.0 μMolTE/gDW in water extract, 124.7 μMolTE/gDW in ethanolic extract, 152.4 μMolTE/gDW in methanolic extract, 92.7 μMolTE/gDW in ethyl acetate extract,and 107.2 μMolTE/gDW in acetone extract). Cichorium intybus L. flowers from the Kosovo region are also a rich source of flavonoids. Further studies are recommended to quantify and isolate the pure phytoconstituents from Cichorium intybus L. flowers grown in the Kosovo region which might serve as natural antioxidants application in the food and drug industry.
