IN VITRO ANTIBACTERIAL PROPERTIES OF ORGANIC EXTRACTS OF Cestrum nocturnum L. (Pages : 7 - 9)

The aim of this study was to test the efficacy of various organic extracts (hexane, chloroform, ethyl acetate and methanol) of Cestrum nocturnum L. as a potential antibacterial agent against some representative food borne pathogenic and spoilage bacteria. The extracts revealed remarkable antibacterial activity against Staphylococcus aureus ATCC 6538, Listeria monocytogenes ATCC 19166, Bacillus subtilis ATCC 6633, Pseudomonas aeruginosa KCTC 2004, Salmonella typhimurium KCTC 2515 and Escherichia coli ATCC 8739. The zones of inhibition of different concentrations of essential oil against the tested bacteria were found in the range of 17.5 ± 1.3 to 9.2 ± 0.6 mm and the MIC values recorded between 62.5 and 1000 µg/ml. The results obtained in this study suggest that the C. nocturnum may have potential use in food, pharmaceuticals and agro industries for preservatives or antimicrobial agents. Download
