Abstract
Češnjak (Allium sativum L.) ima značajnu ulogu u obrani ljudskog organizma od različitih bolesti, zahvaljujućivisokom sadržaju antioksidacijskih tvari. Brojna istraživanja provedena na češnjaku dokazala su prisutnost antioksidacijskihi fenolnih spojeva, nekoliko sumpornih spojeva i vitamina. Cilj ovog istraživanja bio je ispitati razlike u sadržaju ukupnihfenola, askorbinske kiseline i ukupne antioksidacijske aktivnosti četiri kultivara ozimog slavonskog češnjaka, te utvrditipostojanje korelacija između tih parametara. Sadržaj askorbinske kiseline, ukupni sadržaj fenolnih spojeva, te ukupnaantioksidacijska aktivnost četiri kultivara slavonskog ozimog češnjaka određeni su spektrofotometrijski. Genetičkaraznolikost kultivara ozimog slavonskog češnjaka značajno je utjecala na sadržaj askorbinske kiseline i ukupnuantioksidacijsku aktivnost. Ukupna antioksidacijska aktivnost bila je u značajnoj pozitivnoj korelaciji sa sadržajemaskorbinske kiseline (r=0,6495; p=0,006), dok između sadržaja ukupnih fenola i ukupne antioksidacijske aktivnosti nije bilautvrđena značajna povezanost. Kultivar 1 (PFO 1) imao je najveću antioksidacijsku aktivnost (8,006 mol Trolox/g svj.tv.) inajveći sadržaj askorbinske kiseline (8,5705 mg askorbinske kiseline/100 g svj.tv.), a time se pokazao kao najkvalitetniji odčetiri ispitivana kultivara.

Parallel abstract (English)
Garlic (Allium sativum L.) has a significant role in the defence of the human body against various diseases due to thehigh content of antioxidative substances. Numerous studies conducted on garlic, have proved the presence of antioxidants,phenolic compounds, sulfur compounds and several vitamins. The aim of this sudy was to investigate the differences in thecontent of total phenols, ascorbic acid and total antioxidant activities of four winter Slavonian garlic cultivars, and to establishcorrelations between these parameters. The total antioxidant activity and the content of ascorbic acid and total phenols in fourcultivars of winter Slavonian garlic (Allium sativum L.) were determined spectrophotometrically. Genetic diversity of winterSlavonian garlic cultivars (Allium sativum L.) significantly affected the content of ascorbic acid and the total antioxidant activity.The total antioxidant activity significantly positively correlated with the content of ascorbic acid (r = 0.6495, p = 0.006), whilethe content of total phenols and total antioxidant activity were not significantly related. Cultivar 1 (PFO 1) had the highestantioxidant activity (8.006 mol Trolox /g FW) and the highest ascorbic acid content (8.5705 mg ascorbic acid/100 g FW) andtherefore the best quality of the four tested garlic cultivars.
