Abstract :
Trachyspermum ammi L. is a traditional medicinal herb that has been used to cure a variety of diseases in humans. The goal of this study was to evaluate the antibacterial activity of methanolic, ethanolic, and acetonic extracts of T. ammi seeds against a bacterial species. Agar well diffusion method was used to test antibacterial activity. In comparison to methanolic and acetonic extracts, ethanolic extract of T. ammi seeds showed a highest antibacterial activity against P.aeruginosa, K.pneumoniae, and B. cereus. Methanolic extract, on the other hand, effectively inhibited S. aureus and E. coli. The maximum inhibition zone in ethanolic was observed against P. aeruginosa and B. cereus (22.6 mm) and the minimum inhibition zone against E. coli (12 mm) at 100% concentration. Plant extracts contained alkaloids, flavonoids, saponins, tannins, and glycosides.
