The present study was directed to evaluate antioxidant potential of methanolic extract from defatted meal of twenty Exotic collections (EC) of Brassica juncea for selection of desirable breeding germplasm having functional value in term of antioxidative potential. Being antioxidative in nature, B. juncea may be used as an alternative in place of synthetic ones. Total antioxidant activity and phenol content was observed in the range 14.204 to 26.973 mg/g and 5.39 to 7.47 mg/g, respectively. In term of IC50 value Hydroxyl radical, nitric oxide & superoxide radical scavenging was maximum in EC564649 where as DPPH radical scavenging was maximum in EC552583 (YS). Metal chelating activity was maximum in EC564641.
