The studies was defined qualitative and quantitative composition of flavonoids in lichen species Physcia stellaris (L.) Nyl., Collected in habitats with different levels of anthropogenic load. Changes in the composition of flavonoids is considered in the literature as an indicator of the direction of the synthesis of secondary metabolites by plants to protect against adverse environmental influences. It was found that the most diverse number of members (128 compounds), phenolic substances found in the least contaminated RB Ishimbai area and the fewest (58 compounds) was detected in Sterlitamak. Analysis of qualitative and quantitative composition of flavonoids showed that in the area of Ishimbaisky samples were found to accumulate naringin, dihydroquercetin, quercetin. The samples obtained in Alsheyevsky District noted in content highs routine, but samples Sterlitamak – fizetina and naringenin. The calculation of the potential antioxidant status showed that the samples of Ishimbaisky district formed the highest level of protection phenolic substances. It showed no direct correlation between the growth response to environmental pollution and the level of flavonoid content in the thallus of lichens.
