Antilisterial activity of some plants used in folk medicine

Ethanol extracts from six species representing six different families, used in traditional medicine in Turkey were evaluated for their antilisterial activities. The antilisterial activities of Plantago major L., Ononis spinosa L., Lythrum salicaria L., Juglans regia L., Centranthus longiflorus Stev., and Teucrium polium L. were tested against four different Listeria isolates ( L. monocytogenes , L. ivanovii , L. innocua , and L. murrayi ) by the agar diffusion method and the macrodilution method. All plants showed antilisterial activity against L. monocytogenes .
