“…In our study, the tested extracts showed no effect on K. pneumoniae, too. Simonyan et al [42] indicated that methanolic, ethanolic, and acetonic extracts of X. stenophylla collected from Gegharkunik Province, Armenia, showed in vitro antibacterial activity against Grampositive bacteria. In our study, XSA and XSM also showed a good effect on Gram-positive bacteria.…”

The aim of this study was to identify some of the secondary metabolites present in acetonic, methanolic, and hexanic extracts of lichen Xanthoparmelia stenophylla and to examine their antioxidant, antimicrobial, and cytotoxic activity. Compounds of the depsid structure of lecanoric acid, obtusic acid, and atranorin as well as usnic acid with a dibenzofuran structure were identified in the extracts by HPLC. The acetone extract was shown to have the highest total phenolic (167.03 ± 1.12 mg GAE/g) and total flavonoid content (178.84 ± 0.93 mg QE/g) as well as the best antioxidant activity (DPPH IC50 = 81.22 ± 0.54). However, the antimicrobial and antibiofilm tests showed the best activity of hexanic extract, especially against strains of B. cereus, B. subtilis, and S. aureus (MIC < 0.08, and 0.3125 mg/mL, respectively). Additionally, by using the MTT method, the acetonic extract was reported to exhibit a strong cytotoxic effect on the HeLa and HCT-116 cell lines, especially after 72 h (IC50 = 21.17 ± 1.85 and IC50 = 21.48 ± 3.55, respectively). The promising antioxidant, antimicrobial, and cytotoxic effects of Xanthoparmelia stenophylla extracts shown in the current study should be further investigated in vivo and under clinical conditions.

Antimicrobial activity of aqueous, acetone, methanol, and ethanol extracts of saxicolous lichen Lecanora muralis sampled from Odzun, Lori province of Armenia were studied. Aqueous extract was not demonstrated any significant antibacterial activity neither Gram positive nor Gram negative bacteria. All other extracts exhibited antimicrobial activity only against only tested Grampositive bacteria. The minimal inhibitory concentration (MIC) value of acetone extract was 57 μg/μl against Bacillus subtilis.
