This study was designed to examine the antioxidant and free‐radical scavenging activities of two Allium species, Allium roseum and Allium subhirsutum. This study reports the results concerning bulb, stalk and leaf antioxidant enzyme activities (superoxide dismutase, catalase, guaiacol peroxidase and glutathione peroxidase), quantities of malonyldialdehyde, • OH and O 2 •− radicals and total antioxidant capacity determined by the FRAP method. Scavenging activities were determined by ESR method. The total antioxidant capacity was the highest in the leaves of Allium roseum. Among the investigated organs the leaves exhibited the highest antioxidant activities in all investigated Allium species. The highest ESR (84.61%) scavenger activity was observed in the leaves of Allium roseum. Copyright © 2008 John Wiley & Sons, Ltd.
