Antibacterial activities of Stachys lavandulifolia Vahl. extract against eight bacteria

Background & Aim:  Interest in alternative medicine and plant-derived medications that affect the "mind" is growing.  Stachys lavandulifolia Vahl subsp. lavandulifolia (Lamiaceae) is widely used in south Anatolia as herbal tea. It is used for the treatment of gastrointestinal and respiratory disorders. The aim of the present study was to investigate the effects of the hydro-alcoholic extract of Stachys lavanduifolia Vahl against eight bacteria. Experimental:  The present study was done to determine the antimicrobial activity and minimum inhibitory concentration (MIC) of extract Stachys lavandulifolia against human pathogenic bacteria. The antimicrobial effect of ethanolic extracts of Stachys lavandulifolia was determined using a deep-well broth micro dilution method on commercially available bacterial strains. Results: The result indicated that the MICs were observed ranges from 25 to 100 ppm for antibacterial activity of the extract from S. lavandulifolia against eight bacteria. The least MIC value was observed against P. mirabilis and E. faecalis. Recommended applications/industries: It suggests that the extract from Stachys lavanduifolia might be a promising approach for developing new anti-bacterial drugs.
