Abstract: The ethnobotanical and folk medicine used of plant A. monophylla (L.) Corr. Serr. Itis used for Respiratory, Rheumatism etc. To evaluate the plant’s leaves and stem of Atalantia monophylla extract of pet ether, chloroform, acetone and methanol for, total antioxidant and free radical scavenging ability. The ability of the plant extract to act as hydrogen/electrons donor or scavenger of radicals were determined by in-vitro antioxidant assays using 2,2-diphenyl-2-picryl-hydrazyl free radical (DPPH^.) scavenging, then reducing power assay, superoxide radical (O₂^*-) scavenging activity, phosphomolybdenum assay, ferric Reducing antioxidant power assay, and metal chelating activity, were performed to know the antioxidant potency of the plant extract of leaves and stem of Atalantia monophylla. The study also revealed significant free radical scavenging ability of the plant leaves as assessed by DPPH, reducing power, phosphomolybdenum assay, FRAP, and metal chelating activity. Scavenging ability of the plant leaves as assessed by DPPH, reducing power, phosphomolybdenum assay, FRAP, and metal chelating activity.
