abstract = "Species of the genus Allium are used for different purposes: as food (vegetables, spices, flavor agent
in the bakery industry), medical agent in folk medicine, and as decorative perennials. Effect of
onion, garlic and leek on human health have been described in many studies. The presence of
compounds with potential antioxidant activity are considered responsible for their health effect.
Other species of this genus have been intensively studied in recent years in order to estimate their
nutritional value and healing effect. In this paper, the antioxidant activity of edible parts of two
Allium species (Allium nutans and A. odorum) was determined, by DPPH. and ABTS..+ scavenging
assays. The tested species were grown in Serbia, in open field conditions and were foliar treated
with selenium fertilizer (Na2SeO4) in four doses (0, 10, 20 and 30 g per ha), in the phase of
intensive growth. Antioxidant activity was determined spectrophotometrically, by reading the
absorbances of the samples at 515 nm in the case DPPH. assay and at 734 nm in the ABTS.+ assay.
The obtained results were expressed as a percentage of inhibition of DPPH radicals and ABTS
radical cations caused by the action of the extract of the tested Allium species. A. nutans had the
highest antioxidant activity in control variant – without Se treatment (23.77% ± 0.19) in DPPH.
assay, and in variant II - 10 g of selenium fertilizer per ha (69.05 ± 6.06) in ABTS.+ assay. The
highest antioxidant activity of A. odorum was detected in variant IV - 30 g of selenium fertilizer per
ha (25.75 ± 0.28) in DPPH assay. In A. odorum there was no significant difference in antioxidant
activity in the control variant (33.41 ± 0.38) and variant III - 20 g of selenium per ha (33.79 ± 0.46),
in ABTS assay.",
