Abstract

This study aims to investigate the total antioxidant capacity (TAC) as trolox equivalent (mmol g-1) of nineteen edible wild plants traditionally used in Ayvalik using four different assays, CUPRAC, ABTS, FRAP and Folin. The order of ten plants exhibiting the higher capacities could be listed as: Daucus carota (1st wrt CUPRAC, ABTS, and FRAP), Sonchus oleraceus (2nd wrt CUPRAC, ABTS, and FRAP), Sonchus asper (3rd), Rumex pulcher (4th wrt CUPRAC, ABTS, and Folin), Cichorium intybus (5th wrt CUPRAC, ABTS, and Folin), Papaver rhoeas (7th wrt CUPRAC, ABTS, and FRAP), Foeniculum vulgare (8th wrt CUPRAC and FRAP), Urtica pilulifera (6th wrt CUPRAC, 8th wrt Folin), Rumex acetosella (7th wrt Folin, 9th wrt CUPRAC and FRAP), and Nasturtium officinale (11th wrt CUPRAC and Folin). The three edible wild plants (Daucus carota, Sonchus asper subsp. glaucescens and Sonchus oleraceus) with CUPRAC antioxidant capacities of 0.37±0.05, 0.31±0.03, and 0.34±0.05 mmol trolox g-1, respectively, may be considered as a potential source of natural antioxidants to be incorporated in current diets to protect human health. CUPRAC method proved to be most effective among electron-transfer based TAC assays since it responded to a wide variety of hydrophilic and lipophilic antioxidants.
