Previous studies revealed the biochemical profile, in vitro toxicity, and cytotoxic activity of Eragrostis amabilis (L.) Wight. Arn. and Eragrostis pilosa (L.) Beauve and the functional constituents of E. amabilis and E. pilosa using FT-IR. But there is no report on antioxidant activities of E. amabilis E. pilosa aerial and underground parts. With this background, the present study was undertaken to reveal the antioxidant profile of Eragrostis amabilis (L.) Wight. Arn. and Eragrostis pilosa (L.) Beauv. aerial and underground parts using the DPPH, ABTS, FRAP, SOD, metal chelating, and nitric oxide scavenging assays. A dose-dependent DPPH, ABTS, FRAP, SOD, metal chelating, and Nitric Oxide radical scavenging activity was observed in all the studied extracts of E. amabilis and E. pilosa. The aerial parts of E. pilosa and E. amabilis various extracts revealed the maximum antioxidant activities. The correlation values of total antioxidant capacity obtained by these assays were positive at p < 0.01 and (2-tailed) p < 0.05 (1-tailed) significance level, indicating that the values of antioxidant capacities assayed by NO2 assay, DPPH assay, ABTS assay, and SOD assay were highly correlative. The high rate of antioxidant and free radical scavenging potential of E. pilosa and E. amabilis are correlated with their high phenolic content occurrence and identified as a good and valuable alternative source of natural antioxidants.
