Abstract

Chenopodium album (sub sp. striatum) is a folk and nutritious medicine belongs to Chenopodiaceae family and widely used as antimicrobial agent. The aim of this study is to evaluate the in vitro antibacterial potential against multidrug-resistance (MDR) bacteria isolated from clinical spicemens, antioxidant activity, total phenolic and total flavonoids content of crude ethanolic extract and nine different fractions of C. album (sub sp. striatum). The in vitro antibacterial activity was evaluate against eight multidrug-resistant bacteria based on minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC), agar well and disk diffusion methods. Antioxidant property was evaluated by 1, 1-diphenyl-2-picryl-hydrazyl radical scavenging activity. The total phenol contents were measured by Folin-Ciocalteu and AlCl 3 assays. Our results showed that MeOH: H 2 O with 80:20 ratio (most polar) fraction had the highest antimicrobial effect on eight multidrug-resistant bacteria (MIC: 0.15-2.5 mg/ml, MBC: 0.31-5 mg/ml and had highest inhibitation zones (well: 24.33±0.57 mm and disk: 26.33±1.53 mm). In antioxidant assay, MeOH: H 2 O fraction also exhibited the highest radical scavenging activity [Antioxidant activity = 95.1±2.13 percent] and flavonoid content of crude ethanolic extract and most polar fraction were the highest [(0.892±0.011, 0.865±0.010) mg/ml and (4.873±0.029, 4.535±0.025) mg/ml]. According to our result, C. album (sub sp. striatum) has the greatest potential to be consider as antibacterial (against MDR bacteria strain) and antioxidant agent, but further in vivo research, isolation of pure compounds should be carried out to discover the modes of its action and to shed light on the effects.

Investigation of antimicrobial and antioxidant activities of Chenopodium album extracts and their effects on gentamicin nephrotoxicity in rats

“…In biological systems, the compounds that eliminate or destroy reactive oxygen species not only exist in human metabolism, but also in plants and fruits. Chenopodium album has antimicrobial activity against different pathogenic bacteria such as P. multocida, K. pneumoniae, Bacillus cereus, S. aureus, P. aeruginosa, B. subtilis, E. coli, and Y. enterocolitica (Adedapo et al, 2011;Khomarlou et al, 2017;Külcü et al, 2019;Parkash & Patel, 2014). Korcan examined the antibacterial activity of methanolic extract and found that it was most effective against B. subtilis (13 mm zone of inhibition at 100 g mL −1 ), and that the activity increased with increasing the extract concentration (Korcan et al, 2013).…”

“…Ampicillin (20 μg/well) was administered as a control. In vitro, antimicrobial activity was tested by determining the minimum inhibitory concentration (MIC) and minimum lethal concentration (MLC) using micro‐dilution method (Khomarlou et al, 2017 ).…”
