Popis: The objective of this study was to estimate the antibacterial activity of three different herbal extracts against oral bacteria and their bioactive composition.Using the disk diffusion technique, the antibacterial activities of three different extracts (lemongrass, sage, and guava leaf) were evaluated against oral bacteria (Streptococcus mutans, Staphylococcus aureus, and Enterococcus faecalis). Additionally, the bioactive components of the herbal extracts were assessed by employing the gas chromatography-mass spectrometry technique.The sage, lemongrass, and guava leaf extracts suppressed the proliferation of all three tested bacterial strains at different rates. The phytochemical analysis revealed that sage extract possessed the highest content of antioxidants, phenols, and flavonoid compounds. The gas chromatography-mass spectrometry analysis of the tested plants revealed the presence of vital bioactive compounds.Lemongrass, sage, and guava leaf extracts have potent antibacterial activities, are rich in bioactive compounds, and could be utilized as natural remedies for the prevention of oral diseases.
