Özet
The present study evaluated the antimicrobial, anti-quorum-sensing, antibiofilm, and antioxidant activities of Silybum marianum, Scolymus hispanicus, Centaurea urvillei subsp. stepposa, Cirsium arvense subsp. vestitum and Onopordum illyricum. Antimicrobial activity was tested by disc diffusion and microdilution methods, while quorum-sensing inhibition was assessed through violacein inhibition, swarming motility, and anti-quorum-sensing assays. Antioxidant potential was determined by DPPH and FTC methods. S. hispanicus and O. illyricum showed the highest inhibition zones (17 mm) against Staphylococcus aureus MU 47, and O. illyricum had the lowest MIC (5 mg/mL) against Bacillus subtilis ATCC 6633. The highest antibiofilm effect was recorded for S. marianum (41.83%) against Escherichia coli ATCC 25922. S. marianum showed 31.19% violacein inhibition, and C. urvillei subsp. stepposa inhibited swarming motility by 42.9%. O. illyricum extracts displayed the strongest antioxidant activity (IC50 = 5.76 mg/mL for DPPH; 67.79% inhibition by FTC). These findings suggest the studied plants hold promise as natural antimicrobial and antioxidant agents.
