	The current study focuses on the chemical composition, and evaluation of antioxidant and antibacterial activity of the aerial parts of\&nbsp;Centaurea resupinata\&nbsp;subsp.\&nbsp;dufourii. Using different chromatographic methods nine compounds 1{\textendash}9 were isolated. The structural identification of isolated compounds was achieved using several spectroscopic methods NMR techniques (1H NMR,\&nbsp;13C NMR, COSY, HSQC, HMBC) and mass spectroscopy (ESI-MS) and by comparison with literature data. The structures of these compounds were identified as nicotiflorin (1), apigetrin (2), chrysoeriol (3), apigenin (4), chrysin (5), daucosterol (6), β-sitosterol (7), taraxastrerol (8) and lupeol (9). The antibacterial and antioxidant activities of ethyl acetate and\&nbsp;n-butanol extracts have been evaluated. The antioxidant activity was assessed in\&nbsp;vitro using DPPH radical scavenging method, which showed that ethyl acetate extract possessed an interesting antioxidant potential (IC50 = 36.263 {\textpm} 0.005 μg/mL).
