Objective: To determine the antioxidant property of Ageratum houstonianum leaves. Method:\udThe present study was conducted in three different solvent extracts of leaves of Ageratum\udhoustonianum Mill. (Asteraceae) to evaluate the antioxidant properties such as 1,1-diphenyl-2-\udpicrylhydrazyl (DPPH) and hydroxyl radicals which were carried out at various concentrations\udunder in vitro condition. Results: It was found that ethyl acetate extract could scavenge both the\udoxidants at 500毺 g/mL with high percentage inhibition (88.26 暲0.35) of DPPH, and in the case of\udhydroxyl radicals the maximum percentage inhibition was 75.81 暲0.39, which were found to be\udgreater in ethyl acetate extract than in positive controls such as Butylated hydroxytoluene (BHT)\udand ascorbic acid. The next higher inhibitory extract was found to be methanol. Conclusion:\udThis shows that the plant Ageratum houstonianum may be a potent source of natural antioxidan
