Abstract
A reliable source of increased intake of vitamins and biologically active substances are not only berries and fruits, but also herbs. This article is devoted to the analysis of plant samples for antioxidant activity. The objects of study were selected herbs and flowering woody plants of the Samara region: small-leaved linden color (Tilia cordata), medicinal sage (Salvia officinalis L.), medicinal clover (Melilоtus officinalis), currant leaf (Folium Ribes nigrum), wild strawberry (Fragum folium silvam), grapes (Vitis labrusca). Plant material collected in the phase of mass flowering. Aqueous alcoholic extracts (1 : 1 ratio) were obtained from the samples at 37 °C for 2 hours. Anti-radical activity was tested using the free radical DPPH (2,2-diphenyl-1-pilkrilgidrazil), restoring force the FRAP method (Ferric Reduction Antioxidant Power), antioxidant activity in the linoleic acid system and the content of phenols, flavonoids. Analyzing the results obtained in this work, we can conclude about the presence of antioxidant properties. The leader in anti-radical activity and regenerative power was a currant leaf, a high content of phenols has linden color, the maximum content of flavonoids was also recorded in a currant leaf.
