Abstract

Objective: Cardamom is commonly known as queen of spices for the versatile use in culinary practice. This study carried out to determine whether seeds, leaves aqueous extract and crude oil of cardamom (Elettaria Cardamomum Maton) has inhibitory activity on some pathogenic bacteria isolated from different clinical samples. Methods: In vitro antimicrobial activity of Elettaria cardamomum fruit extract, leaves and oil were studied against Staphylococcus aureus, S. epidermidis, Streptococcus pneumonia, Pseudomonas aeroginosa, Proteus mirabilis,Klebsiella pneumonia, Enterobacter spp. Acinetobacter, E. coli, Serretia spp. and Salmonella typhi. The inhibitory effect of extracts were compared with standard antibiotic ciprofloxacin. Results: The largest mean zone of inhibition was obtained with the oil of fruits (35mm) and fruit aqoues extract and their leaves extract (30mm) this study depicts that the oil, leaves and fruit extract ofElettariacardamomum can be used as potential source of novelantimicrobial agents used for different types of bacteria in different infections. On the basis of the experimental results and discussion, it can be postulated that the aqueous seed, leaves extracts and crude oil of cardamom possesses the potent antimicrobial properties. These extracts have an active against Salmonella typhi Gram positive and Gram negative bacteria. Conclusions: Most of cardamom’s extracts show high antibacterial activity against both gram positive and gram negative bacteria, therefore cardamom can provide protection to a certain extent against our natural enemies like bacterial pathogens

Keywords: Elettaria cardamomum, zone of inhibition, different bacteria.
