Abstract: Tuberculosis, caused by Mycobacterium tuberculosis, is a major public health problem worldwide, as it is associated with high rates of morbidity and mortality. In addition, infections by non-tuberculous mycobacteria, such as M. smegmatis, represent a growing concern, especially in immunocompromised individuals. Faced with the challenge of increasing resistance to conventional treatments, the search for new antimycobacterial agents of natural origin emerges as a promising alternative for the treatment of these infections. The screening of medicinal plants is one of the alternatives currently employed in the search for new compounds capable of overcoming antimicrobial resistance mechanisms. Therefore, this study aimed to conduct a review on the antimycobacterial activity of natural products. For this purpose, an integrative literature review was carried out in the Scientific Direct, Scopus and PubMed databases, adopting the Health Sciences Descriptors (DeCS): “Mycobacterium”; “Non-tuberculous mycobacteria”; “Natural products”; “Antimycobacterials”. Studies published between 2008 and 2024 were selected. The results indicate that phenolic compounds extracted from medicinal plants, including flavonoids (luteolin, naringenin, quercetin-3-O-glucoside, isoorientin, orientin and hesperidin) and phenolic acids (caffeic acid, rosmarinic acid and artemisinic acid), represent molecules with promising activity against M. tuberculosis and non-tuberculous mycobacterial species, especially M. smegmatis. These findings reinforce the importance of investing in research on natural products as alternative sources of new antimicrobial agents. In addition, the development of therapeutic strategies based on compounds of natural origin can significantly contribute to reducing the global problem of antibiotic resistance and improving public health.
