We investigated antioxidant and radical scavenging activity of lyophilized aqueous extract and ethanol extract of roots and barks of Turkish liquorices (Glycyrrhiza glabra L.) by employing various in vitro antioxidant assays such as DPPH center dot scavenging activity, ABTS center dot+ scavenging activity, DMPD center dot+ scavenging activity, O2 center dot- scavenging activity, total antioxidant activity, Fe3+-Fe2+ and Cu2+-Cu+ reducing abilities H2O2 scavenging and ferrous ions (Fe2+) chelating activities. Aqueous extract of aerial parts (AE-AP), ethanol extract of aerial parts (EE-AP), aqueous extract of root parts (AE-RP) and ethanol extract of root parts (EE-RP) of Turkish liquorices inhibited 87.9, 83.6, 88.6 and 80.1% lipid peroxidation of linoleic acid emulsion at 30 g/mL concentration, respectively. On the other hand, -tocopherol and trolox indicated inhibition of 68.1 and 81.3%, respectively.
