Table 3.
Antioxidant activity of extracts from Agastache foeniculum, Artemisia absinthium, Evernia prunastri, Humulus lupulus, Laurus nobilis, Origanum vulgare, Vaccinium myrtillus and sunflower honey. Results are given as mean values of three independent replicates ± standard deviation.

* Different letters within a column denote significant differences (p < 0.05). For the CUPRAC value: a Artemisia absinthium and Origanum vulgare different from the others’ samples (p < 0.05); b Agastache foeniculum, Evernia prunastri, Humulus lupulus, Laurus nobilis and Vaccinium myrtillus different from the others’ samples (p < 0.05); c Vaccinium myrtillus, Humulus lupulus and sunflower honey were different from the others’ samples (p < 0.05); (Results were analysed using the SPSS programme); d Laurus nobilis, Origanum vulgare Sunflower honey, Agastache foeniculum, Artemisia absinthium, Evernia prunastri and Humulus lupulus different from the others’ samples (p < 0.05); TE: Trolox equivalents, DW: dry weight.
