Abstract: (129 Views)
Artemisia sieberi plant (Artemisia sieberi), one of the Artemisia species with wide distribution in Iran and the Middle East, has received attention due to its various medicinal properties, including antimicrobial effects. The aim of this study was to determine the total phenolic and flavonoid content, antioxidant activity (DPPH and ABTS radical scavenging), and antimicrobial activity (agar disk and well diffusion, minimum inhibitory concentration, and minimum bactericidal concentration) of the essential oil of Artemisia sieberi. The total phenolic and flavonoid contents were determined to be 44.62 ± 5.30 mg gallic acid equivalent (GAE)/g and 18.20 ± 2.90 mg quercetin equivalent (QE)/g, respectively. Antioxidant activity, expressed as the percentage of DPPH and ABTS radical scavenging, was found to be 58.26 ± 1.57% and 63.74 ± 1.42%, respectively. The results of the antimicrobial activity evaluation, using both disk diffusion and well diffusion methods, demonstrated that the Gram-positive bacteria Streptococcus pyogenes and Listeria monocytogenes were the most susceptible strains to Artemisia sieberi essential oil. The minimum inhibitory concentration of this essential oil against the Gram-positive bacteria Streptococcus pyogenes, Listeria monocytogenes, and Bacillus cereus was determined to be 8 mg/mL, 128 mg/mL, and 128 mg/mL, respectively. Furthermore, this essential oil was effective against Gram-negative bacteria such as Shigella dysenteriae and Salmonella typhimurium at a concentration of 512 mg/mL, except for Klebsiella pneumoniae, which showed sensitivity at a concentration of 256 mg/mL. Therefore, Siberian wormwood essential oil can be used as an effective natural antimicrobial agent against bacterial infections.
Keywords: Artemisia sieberi, minimum inhibitory concentration, minimum bactericidal concentration, DPPH free radical, ABTS free radical.
