Abstrakt
The antioxidant properties of different matrices can be determined using various
methods. In this work, two spectrophotometric methods based on the scavenging
activity of the radicals DPPH (2,2-diphenyl-1-picrylhydrazyl) and ABTS (2,2’-
azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)) were used together with a
spectrophotometric method based on the ferric reduction power of phenolic
compounds. The results obtained using all three methods were compared and
discussed for infusions prepared from different parts of stinging nettle (Urtica
dioica L.). The relation with the time of harvest and location of grow were also
examined. Finally, the antioxidant capacity of all the studied nettle infusions were
correlated with the total phenolic content determined using Folin–Ciocalteu
reagent.
