Resumen

The importance of this research lies according to SDG 3 “Health and well-being” in promoting well-being for all at all ages, and thus ensuring sustainable development, with the objective of determining the antibacterial effect of Rosmarinus officinalis “rosemary” on the viability of Streptococcus mutans. This research was experimental with increasing stimulus design, it was carried out with the Kirby-Bauer method using Mueller Hinton Agar supplemented with blood. Agar diffusion was used to determine antimicrobial activity. The study had the following experimental groups: 25%, 50%, 75%, 100% of “rosemary” extracts. According to literature, the phytoconstituents present in “rosemary” leaves are: Phenolic acids, 1,8 cineole, Camphor, a pinene, bornyl acetate, flavonoids and triterpenes. It was demonstrated that the "rosemary" extract at a concentration of 75% has a high antimicrobial activity against S. mutans, observing an inhibition zone that varies between 14 to 16.83 mm. It is concluded that the "rosemary" extract in concentrations greater than 75% has a greater antimicrobial effect on S. mutans. Likewise, it was observed that the minimum inhibitory concentration (MIC) of the rosemary extract showed inhibition of 1 mg/dl, compared to the S. mutans.
