Abstrakt
Oceniono zawartość polifenoli, flawonoidów i aktywność antyoksydacyjną ekstraktów z cebuli (Allium cepa L.), czosnku (Allium sativum L.), mięty zielonej (Mentha spicata) i mięty pieprzowej (Mentha × piperita). Wszystkie ekstrakty wykazały szeroki zakres całkowitej zawartości polifenoli od 15,10 do 83,90 mg GAE 100 g–1 równoważnika kwasu galusowego, oraz całkowitej zawartości flawonoidów, średnio 0,50 do 9,2 mg ∙ 100 g–1 odpowiednik katechiny. Aktywność przeciwutleniającą (AA) oznaczono przez pomiar siły wychwytywania 2,2-difenylo-1-pikrylohydrazylem (DPPH). Aktywność wychwytywania rodników DPPH (wartości IC50) różnych ekstraktów wahała się od 29,9 do 73,4%. Wyniki badań laboratoryjnych analizowano statystycznie, stosując odpowiednie metody statystyczne.
