Objective: In the present study, antioxidant activity in the leaf of the pet-ether, chloroform, acetone and methanolic extracts from Litsea laevigata Gamble. Leaf was investigated by employing established in vitro studies. L. laevigata belongs to the Lauraceae family.

Methods: The capability 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-picrylhydrazyl free radical (DPPH.) scavenging, reducing power assay, superoxide radical (O2*-) scavenging activity, phosphomolybdenum assay, FRAP, ABT and metal chelating activity were performed to know the antioxidant potency of the plant extract of leaves of L. laevigata.

Results: 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 IC50 antioxidant activity of DPPH assay (5.264 µg/ml) and compare to other extract, higher phosphomolybdenum reduction (164.36 mg/g), better Reducing power activity leaf in methanol (0.711%), higher ferric reducing power (4060.66MmolFe(II)E/mg), and higher in superoxide radical scavenging activity in (78.12 mg/ml). However, the better metal chelating ability was shown by the water extracts of the leaf (5.145 EDTAE/100g) compared to other solvent extracts.

Conclusion: The result indicates the total phenol and antioxidant activity potential of L. laevigata.
