Persian shallot, Allium hirtifolium Boiss. (AH), is an Iranian native medicinal plant belongs to Alliaceae family. Here, we investigated in vitro antibacterial activity of hydro-alcoholic extract derived from bulbs of AH. We also employed in silico molecular docking to decipher mechanisms of its antibacterial effects. Minimum inhibitory concentrations (MIC) and minimum bactericidal concentration (MBC) against E. coli ATCC 25922 were determined. Molecular docking was performed for major phytochemicals of AH against ribosome recycling factor (RRF). E. coli ATCC 25922 was gentamicin-resistant while AH showed MIC (42 ± 18 lg/ml) and MBC (106 ± 36 lg/ml) against E. coli. In silico results reported all phytochemicals of AH shown acceptable negative binding affinity (kcal/-mol) with RRF.
