Abstract
In the current study, the processing of gamma irradiation on Vigna aconitifolia was carried out at various doses (2,5, 10, 15 and 25 kGy). The total free phenolics content, 1, 1- diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging, hydroxyl radical scavenging activity, superoxide radical scavenging, ABTS+ cation radical scavenging activities and reducing power capacity of both untreated and treated samples extracted in methanol were assessed. The total free phenolics content was found to increase from 1.46 % for the untreated sample to 45.20% for 25 kGy radiation-processed sample. Gamma irradiation enhanced all the investigated scavenging activities.
