Abstract

The present study was designated to evaluate the antibacterial activities of aqueous, methanolic and hydro alcoholic extracts from airial parts of Stachys turcomanica against different pathogenic bacteria using broth micro-dilution and Agar Well Diffusion (AWD) assay. The extracts of S. turcomanica in were active against the gram-positive bacteria, Staphylococcus aureus (inhibition zone = 16.5 mm) and virtually inactive against the other gram-positive and gram-negative bacteria (Listeria monocytogenes, E. coli and S. typhimurium). The hydro-alcoholic extract of this plant in broth micro-dilution assay, showed higher antimicrobial activity compared to aqueous and methanolic extracts (MIC= 12.5 mg ml-1 for E. coli and S. typhimurium). Results showed good antibacterial activity for this extract on S. aureus, which suggest its capacity as a natural food preservative.
