Objective: In the present study, antioxidant activity in the leaf of the pet -ether, chloroform, acetone and methanolic extracts from Litsea laevigata Gamble . Method s: The capability of the plant extract to act as hydrogen/electrons donor or scavenger of radicals were determined by Leaf was investigated by employing established in vitro studies. L. laevigata belongs to the Lauraceae family. in vitro antioxidant assays using 2,2 -diphenyl -2-picrylhydrazyl free radical (DPPH . ) scavenging , reducing power assay, superoxide radical (O 2 *- Result s: Results are evaluated higher in leaf extract of L. laevigata recorded total phenol , total flavonoid , and tannin. The present state of work was designed to evaluate the phytochemical, antioxidant in the plant leaf extracts of L. laevigata . The plant L. laevigata methanolic extract of leaf showed greater IC 50 antioxidant activity of DPPH assay ( 5.264 μg /ml ) and compare to other extract, higher ph osphomolybdenum reduction (164.36 mg/g) , better Reducing power activity leaf in methanol (0. 711% ), highe r ferric reducing power (4060.66 MmolFe(II)E/mg ), and higher in superoxide radi cal scavenging activity in (78.1 2 mg /ml ). However, the better metal chelating ability was shown by t he water extracts of the leaf (5.145 EDTAE/100g) compared to other solvent extrac
