Anotace: Wild garlic (Allium ursinum L.) is a member of the Allium genus. However, wild garlic is still unexplored. To date, there are few

publications that deal with this Allium species. The samples of plant material were collected from the three areas near Bratislava
(Bratislava region), Krajné (Trenčin region) and Becherov (Prešov region). The aim of this study was to analyse the content of total
polyphenols (TPC) and the value antioxidant activity (AOA) in selected morphological parts of wild garlic. The samples of wild garlic
were homogenized and a methanolic extract was prepared. These extracts were used for analyses. Total polyphenol content in the
samples ranged from 253.19 ± 5.72 mg GAE.kg-1 FW (bulbs from area Becherov) to 1069.51 ± 5.49 mg GAE.kg-1 FW (leaves from area
Krajne). The values of antioxidant activity were from 2.54 ± 0.83 (bulbs from area Krajne) to 47.98 ± 0.54 % inhibition (leaves from
area Bratislava).
