The purpose of the study was to assess total Flavonoids (TF), total phenols (TP) and antioxidant activity (TAA) in the ethanolic leaf, seed and root extract of Cajanus cajan. Total phenolic content, Total Flavonoids content were measured by using standard procedures and free radical scavenging activities were performed by using DPPH radical scavenging activity, Hydrogen peroxide radical scavenging and phosphomolybdenum assay. The result indicated that total phenolic content in the analysed leaf, seed and root extracts ranged as 55.03mgGAE and 57.20mgGAE, 50.95mgGAE. Similarly Flavonoids content in the analyzed leaf, seed and root extracts ranged as 36.17 mgREgram, 49.43 mgREgram, and 48.32mgREgram. The outcome of the antioxidant activity were found to be dosage dependent .The IC50values for DPPH assay for ethanolic extract of leaf, seed and root were 1.407, 0.844 and 1.184mgml respectively. The highest hydroxyl radical scavenging activity reached up to 79.07% in seed 76.45% in leaf 75.21% in root extracts respectively. The highest total antioxidant potentials observed in Cajanus cajan seed extract compared to other extracts. All the assays tested, it was found that the seed extract possessed highest antioxidant activity.  These findings indicated that potential antioxidant activity were found in Cajanus cajan leaf, seed and root extracts and needs further exploration for their effective use. The high amount of TFC, TPC, and TAA in the leaf, seed and root of Cajanus cajan, makes Cajanus cajan effective free radical scavenger and a powerful source of natural antioxidants.
