Screening of some plant materials used in Armenian traditional medicine for their antimicrobial activity Biology

Abstract

Nowadays, in the era of widespread antibiotic resistance, plants are considered as one of most prospective sources for new antimicrobial compounds. The goal of our research was to screen the antimicrobial efficiency of 48 plant parts of 28 wild plants species, which are commonly used in Armenian folk medicine. Maceration technique was used to obtain plant crude extracts. Antimicrobial activity of plant materials was evaluated by agar well diffusion assay against five bacterial and two yeast strains. Agrimonia eupatoria, Hypericum alpestre, Lilium armenum, Sanguisorba officinalis and Rumex obtusifolius expressed the highest and broadest antimicrobial activity against tested strains and they were selected for further comprehensive studies.
