Sažetak
Rad je koncipiran sa ciljem da se ispita antioksidativna aktivnost etanolskog ekstrakta napravljenog ultrazvučnom ekstrakcijom vrste praziluka, Allium porrum L. U ovim ispitivanjima pripremljeni su etanolni (50 vol.%) ekstrakti jestivih delova praziluka odnosno stabla i lista postupkom ultrazvučne ekstrakcije, a potom je određen sadržaj ukupnih fenola, flavonoida i antioksidativna aktivnost. Ukupni fenoli su određeni metodom po Folin-Ciocalteu, dok je antioksidativno delovanje određeno DPPH 'scavenging' metodom. Dobijeni rezultati za antioksidativnu aktivnost su upoređeni sa kontrolnim antioksidantima: vitaminom C i BHT. Veća količina fenola (69,46 mg GAE/g suvog ekstrakta) i flavonoida (33,53 mg CE/g suvog ekstrakta) nađena je u etanolnom ekstraktu stabla praziluka. Vrednosti IC50 iznosile su 98,90 μg/ml za etanolski ekstrakt lista i 61,05 μg/ml za etanolni ekstrakt stabla praziluka.
