        abstract = {The alarming rise in antimicrobial resistance has intensified the search for novel, plant-based therapeutic agents with broad-spectrum efficacy. Plants from the Tagetes genus, commonly known as marigolds, are widely used in traditional medicine for their antimicrobial, anti- inflammatory, and antioxidant properties. While much of the focus has been placed on marigold flowers, the leaves remain relatively underexplored despite their potential to contain potent bioactive compounds. This study aims to evaluate the antimicrobial activity of ethanolic extracts from Tagetes spp. leaves against selected pathogenic bacterial strains, including Staphylococcus aureus, Bacillus subtilis, Escherichia coli, and Candida albicans. Leaf samples were shade-dried, ground, and subjected to ethanol extraction using cold maceration. Antimicrobial efficacy was assessed via agar well diffusion assay and zone of inhibitory determination. The results demonstrated that the marigold leaf extract showed promising antibacterial activity, particularly against Gram-positive bacteria, with inhibition zones ranging from moderate to high. Phytochemical screening revealed the presence of flavonoids, alkaloids, phenolics, saponins, and tannins, which are compounds known to contribute to antimicrobial mechanisms. These findings indicate that Tagetes spp. leaves could serve as a cost-effective, natural source of antibacterial agents.},
