Abstract
Many of today’s industrial medicines had their origins in the kingdom of plants. Medicinal plants (Herbal medicines) are traditional medicines that mainly treat patients with pharmaceutical preparations. Among the many medicinal plants available, one of the most popular and therapeutic plants is syzygium aromaticum Clove.
Method: In this study Clove of was bought from the local market in Erbil. Gram-positive (Staphylococcus aureus and Staphylococcus epidermidis) Gram-negative Escherichia coli and pseudomonas aeruginosa) were collected from Microbiology laboratory in Tishk International University. The extraction of dried clove bud was done through maceration with applying gentle heat. Furthermore, antimicrobial activity was carried out by the Disk diffusion method. However, one antibiotic (amikacin) was tested for their activity against the mentioned bacteria.
Results: the tested extraction exerted good antimicrobial activity against gram-positive bacteria (Staphylococcus aureus and Staphylococcus epidermidis) with an inhibition zone of 32 mm and 25 mm respectively while it showed less effect toward gram-negative bacteria (Escherichia coli) with an inhibition zone of 10 mm and Pseudomonas aeruginosa with 12 mm. Furthermore, Pseudomonas aeruginosa showed resistance toward Amikacin tested while other bacteria (Escherichia coli, Staphylococcus aureus and Staphylococcus epidermidis) exhibited different inhibition zone with (17, 36 and 23) mm respectively. Conclusion: The results of this study confirmed the antimicrobial ability of Clove against bacteria especially gram-positive bacteria.
