Abstract: The antioxidant properties of methanol extract of Allium scorodoprasum bulb and seed were evaluated, through determination of total phenolics and flavonoids content, as well as DPPH• (1,1-diphenyl-2-picrylhydrazyl) radical scavenging and ferric thiocyanate methods. Bulb extract showed greater reducing power (AEAC value per 1 mg of dry extract for bulb was 6.00 ± 1.03 mg) and ability to scavenge DPPH radical, as well as total phenolic (36.692 ± 4.475 μg GA/mg of dried bulb extract) and flavonoid content. Total phenolic and flavonoid content assay were correlated with ferric reducing power and “scavenging” radical capacity test, and correlation among them was significant. Our research showed that Allium scorodoprasum can be considered as plant with antioxidant compounds.
