dc.description.abstract |
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 the 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 influence of harvest time and location was also examined. The antioxidant capacity of all studied nettle infusions were correlated with the total phenolic content determined using Folin-Ciocalteu reagent. |

Antioxidační vlastnosti látek v různých matricích mohou být stanoveny různými metodami. V této práci byly použity metody DPPH, ABTS a FRAP. Výsledky získané těmito technikami byly porovnány a diskutovány. |
