Abstract

Quercus baloot fractions were subjected to antibacterial susceptibility evaluation that illustrated inhibition zones against Staphylococcus aureusMicrococcus luteusBacillus subtilis,Escherichia coliand Pseudomonas aeruginosa. The active fractions were chromatographed by thin layer chromatography (TLC) and then contact bioautography was utilized as hyphenated bioassay, which showed inhibition zones at different Rf values against B. subtilis, M. luteus, E. coli, and S. aureus. The minimum inhibitory concentrations (MICs) of active fractions were found using a 96-well micro-titer plate method and the non-viability of the organisms was ascertained by determining the minimum bactericidal concentration (MBC) of the fractions. This is the first report of antibacterial activities for Q. baloot.

 

Key words: Quercus baloot, contact bioautography, minimum inhibitory concentration (MIC),minimum bactericidal concentration (MBC).
