The Antibacterial Activity of the Ajowan Extract

Trachyspermumammi or ajowan or ajwain is a plant which its seeds are used as a spice in many of Asian countries such as egypt, India, Pakistan, and Iran.Thymol in Ajwain seeds, is known as a strong germicide, anti-spasmodic. It is also used for cleaning the wounds and treating skin infections. Here, we aim to study the inhibitory effect of Ajowan extract on the microorganisms growth like Escherichia-coli(E-coli), kelebsiella, and staphylococcus,andStreptococcus pneumoniae. Antibacterial activities of Ajowan extract has been evaluated against two gram negative bacteria; Kelebsiella and Escherichia coli and two gram positive bacteria; Streptococcus pneumoniae and Staphylococcus aureus.Minimum inhibitory concentration (MIC) value was determined against all the selected bacteria. The antibacterial activity of Ajowan extract was observed against all selected pathogens with different MIC. The extract was effective for S.aureus with MIC 1.25 mg/ml and Streptococcus pneumonia 2.5mg/ml and followed by E.coli with MIC 2.5 mg/ml, and Kelebsiella with MIC 5. The results of our study showed that the Ajowan extract has effective antibacterial agents against human pathogens which are resistance to antibiotics. More studies should be done to show the detailed mechanism of its antimicrobial effect.
