Summary: | Lichens are symbiotic nature and produce unique secondary extracellular metabolites with high biological activity. In this paper, we compared the antioxidant and antimicrobial activity of two lichen species. Furthermore, we determined the quantitative content of antioxidants of low molecular weight and antimicrobial activity of 40% of the water ethyl extracts of Cetraria islandica and Cladonia arbuscula lichens depending on the layers’ treatment methods and the ratio of dilution of the dry extract with water. Live parts of dried lichens collected in an ecologically clean area of Yakutia were used for extraction. The antioxidant activity of the water-ethanol extract of lichens was performed using a spectrophotometric method. Antimicrobial activity was established using the discodiffusion method in agar in various dilutions of dry lichen extract. The highest antioxidants of low molecular weight were found in Cetraria islandica in distilled water with solid to solvent ratio of 1:1 and in the Cladonia arbuscula ... |
