Abstract

Antioxidants are capable of inhibiting oxidative reactions which produces free radicals in the body responsible for various diseases. In current decade, attention is being given on plants having antioxidant property to replace synthetic antioxidants.  Leucas aspera (Willd.) Link (Lamiaceae), a wild edible vegetable was analyzed to determine antioxidant property of methanolic leaf extract by 2,2-Diphenyl-1-picrylhydrazyl (DPPH) assay and IC50 was calculated by plotting nonlinear regression curve. The total phenolic content (TPC) was determined by Folin-Ciocalteu’s method using gallic acid as standard. L. aspera exhibit potent antioxidant property with IC50 value 54.78µg/ml. Total phenolic content was found to be 45.30 ± 0.64 mg GAE/g dry extract. L. aspera which is consumed as common vegetable in Sonitpur district of Assam (India) are potent source of antioxidants and can be recommended as healthy vegetable.

Keywords: DPPH, Free radical scavenging activity, IC50, TPC
