ABSTRACT
The aim of the study was to screen the medicinal and antibacterial activities of methanol and acetone extracts of the two spices Fenugreek (Trigonella foenum L.) and Coriander (Coriandrum sativum L.) available in Bangladesh. Crude extract of the spices with methanol and acetone were screened for antibacterial activities against four Gram negative pathogenic bacteria -Pseudomonas spp., Escherichia coli, Shigella dysentiriae and Salmonella typhi. The in vitro antibacterial activity was performed by agar well diffusion method. Methanol extract of Fenugreek and Coriander revealed an elevated antimicrobial activity against Pseudomonas spp. whereas acetone extract of spices exhibited highest activity against Escherichia coli. Acetone extract of Fenugreek and Coriander showed no activity against Salmonella typhi. The results obtained in the present study suggest that the methanol extract of Trigonella foenum Linn. and Coriandrum sativum Linn.revealed a significant scope to develop a novel broad spectrum of antibacterial herbal formulation.
