Rosmarinic acid Antibacterial effect: Rosmarinic acid has broad-spectrum antimicrobial activity and has inhibitory effects on both bacteria and fungi. Rosmarinic acid has obvious inhibitory effect on Bacillus subtilis, Micrococcus luteus, Escherichia coli, Staphylococcus aureus, and Ralstonia solani. Neusa et al. found that rosmarinic acid can inhibit the growth and biofilm formation of Streptococcus caries and Streptococcus mutans, reducing their glucosyltransferase activity, indicating that rosmarinic acid can be used for the prevention and treatment of oral diseases. Research on the antibacterial mechanism of rosmarinic acid shows that on the one hand, rosmarinic acid can increase the permeability of bacterial cell membranes, causing a large amount of leakage of sugars and proteins, and affecting normal bacterial metabolism; On the other hand, it can also affect bacterial protein metabolism and inhibit TaqDNA polymerase.
