DaisyP. SelvakumarbB. N.4200724Methanol extracts of Eugenia jambolana seeds (Myrtaceae), used as a traditional folklore medicine, showed inhibitory effects against the growth of a few multidrug-resistant extended spectrum beta lactamase (ESβL) producing gram-negative bacteria. Bioactivity guided fractionation yielded several fractions. One active flavonoid-containing fraction had a Minimum Inhibitory Concentration (MIC) of 7.9 to 1000 μg mL-1. The strong in vitro antibacterial activity of flavonoid derivatives against ESβL producing gram-negative bacteria suggests the compounds might find wide pharmaceutical use.]]>Ahmad, I.,1994E. coli of man and animals: Compatibility with R-plasmids.]]>1994Ayafor, J.F., M.H.K.
