The results obtained from the screening of the seed extracts of 21 Scottish plants were very promising, especially, the activity of the MeOH extracts of Centaurium erythraea (MIC=1.0 mg/ml) and Prunus padus (MIC=0.01 mg/ml) against methicillin resistant Staphylococcus aureus ( Table 2). n-Hexane and dichloromethane extracts did not show any antibacterial activity at test concentrations. All antibacterial activity was due to the MeOH extracts. Among the MeOH extracts of 21 plant species, 11 showed antibacterial activity against one or more bacterial species. Malva moschata and P. padus were active against five bacterial species, Reseda lutea against four, C. erythraea and Crithmum maritimum against three, Calluna vulgaris against two, and Armeria maritima, Centaurea scabiosa, Daucus carota, Rosa canina and Stellaria holostea against one bacterial species.
