Raw materials of some plants growing in Ukraine – the roots of Arctium lappa L., Glycyrrhíza glabra L., Sanguisorba officinalis L., the fruits of Rosa cinnamomea L.- were been used to investigation of its antioxidant properties. The total phenolic content of prepared aqueous extracts was determined using Folin-Ciocalteu reagent; it ranged from 43.2±2.09 to 98.5±4.01 mg GAE per 100 ml of the extract. The highest vitamin C content was found in the extracts from the rose hips and the great burnet roots - 8.94±0.234 and 7,68±0.341 mg / 100 ml of extract, respectively. Free radical scavenging capacity of the extracts was evaluated using 2,2-diphenyl-1-picrylhydrazyl (DPPH). It ranged from 0.60± 0.0178 to 8.45± 0.26 mM of the ascorbic acid equivalent (AAE) antioxidant capacity per 100 ml of the extract. The highest antioxidant activity was determined for the extract of great burnet roots. The results showed that tested extracts possess potent antioxidant activity and may be considered as natural source of antioxidants.
