Medicinal and aromatic plants have become a part of complementary medicine worldwide because of their potential health benefits, as raw materials for traditional as well as modern medicine. This study aimed to assess the effectiveness of crude solvent extracts, specifically ethyl acetate and chloroform extracts, as well as phytochemical extracts from the leaves of Pimenta dioica, a medicinal aromatic plant from South India, against pathogenic bacteria. The evaluation will be performed via a disc diffusion assay, and phytochemical analysis of the leaves of P. dioica has shown the presence of saponins, alkaloids, tannins, flavonoids, glycosides, terpenoids, polyphenols, and anthocyanins. The results indicated that chloroform extract has shown maximum inhibitory activity compared with ethyl acetate extract and that terpenoid extract has maximum inhibitory activity compared with the other phytochemical extracts.
