Özet: Phytochemical studies of the aerial parts of Bidens cernua L. led to the isolation of six flavonoids: luteolin (1), flavanomarein (2), tilianin (3), maritimetin (4), cynaroside (5) and cosmosiin (6). The quantitative analysis of flavonoids exhibited 0.81% contents of flavonoids in flowers and 1.62% in the herb counted as a hyperoside equivalent. Total Tannins Content showed the occurrence of 7.87% in flowers and 5.83% in the herb. The chemical composition of the essential oil obtained from the herb of B. cernua was evaluated in 92.2%, which corresponds to 99 compounds. Antimicrobial activity of the essential oil was evaluated on Gram-positive, Gram-negative bacteria and fungi. The oil exhibited a strong antibacterial and antifungal activity, especially against Gram-positive bacterial strains. T his is the first time the aforementioned compound (3) has been isolated from B. cernua.
