Summary:The present study investigates the antioxidant activity of 28 wild edible plants (WEPs) resources of Loktak Lake wetland ecosystem of Manipur, North East Indian Himalayan Region and their correlation with phenolics and flavonoids. Antioxidant activity was measured by DPPH, ABTS and FRAP assay. The antioxidant capacity was found to wide ranges of 1.71 to 263.7 µM TEAC/g fresh weight. In three assays, maximum antioxidant capacity is in same order L. (D. Don) Moore > L. ranging from 99.5 to 263.7 µM TEAC/g fresh weight. The correlation study established that all the three antioxidant assays are positively correlated and phenolics have contributed more in antioxidant activity than flavonoids. Among 28 WEPs, L. and (D. Don) Moore were found to be most promising. These plants can be used as source of natural antioxidant additives, nutritional supplements or ingredients of functional foods.
