Identification of chemical compounds and antimicrobial effects of essential oils of Artemisia scoparia and A. Aucheri
Journal Title: International Journal of Farming and Allied Sciences - Year 2015, Vol 4, Issue 6
Abstract
Using of antimicrobial compositions from medicinal plants against bacteria is growing up with respect to resist the bacteria in relation to derived antibiotics from microorganisms. Hence, identification of chemical compounds of herbal oils, which are natural elements, are necessary to create scientific fundaments. In exchange for this matter, antimicrobial effects of Artemisia scoparia and A. Aucheri, which saliently are used in modern and traditional medicine, on Staphylococcus aureus, S. epidermidis, Escherichia coli, and Salmonella typhimurium were studied. Aerial parts of these species were phonologically collected at flowering period and after shrivelling in vitro setting, extracting of essence was done by Hydrodistilation method. Identification and analysis of chemical compositions of the essential oils were done by measuring the Retention Index and Mass spectrums using GC and GC/MS. The antimicrobial effects of the essential oils on bacteria were surveyed by micro-dilution broth method to determine the MIC and MBC and diffusion disk method to determine the areola diameter of lack of bacteria growth. The most and least effective components were accordingly detected in A. scoparia with 97.83% and A. Aucheri with 97.22%, respectively. The essential oil of A. scoparia was more effective on S. aureus and S. typhimurium bacteria while the resistance of E. coli in contradistinction to the essential oils of A. Aucheri was more than other species. The result showed that the essences of these herbs had considerable antimicrobial effects on growing of bacteria or equal to synthetic antibiotics at the minimum assumed situation.
