Abstract
The aim of the study was to screen the antibacterial activities of ethanolic and aqueous-ethanolic extracts of Coriander (Coriandrum sativum) on some microorganisms including Bacillus subtilis, Staphylococcus aureus, Proteus vulgaris, Escherechia coil, Pseudomonas aeruginosa, Klebsiella peunomonia, Listeria monocytogenes, and Candida albicans. According to findings, both ethanolic and Aqueous-ethanolic extract of coriander seed displayed a variable degree of antimicrobial activity on different microrganisms. The ethanolic extract showed clear difference and more potent against tested microorganisms in comparison with the aqueous-ethanolic extract. It is determined that Ethanol extract revealed an elevated antimicrobial activity against Proteus vulgaris and Candida albicans whereas aqueous-ethanolic extract of spices exhibited highest activity against Bacillus subtilis and Listeria monocytogenes. The results obtained in the present study suggest that the ethanol extract of Coriander revealed a significant scope to develop a novel broad spectrum of antibacterial herbal formulation.
