Journal Title: Asian Pacific Journal of Tropical Disease - Year 2012, Vol 2, Issue 0
Abstract
Objective: To determine the antioxidant property of Ageratum houstonianum leaves. Method: The present study was conducted in three different solvent extracts of leaves of Ageratum houstonianum Mill. (Asteraceae) to evaluate the antioxidant properties such as 1,1-diphenyl-2- picrylhydrazyl (DPPH) and hydroxyl radicals which were carried out at various concentrations under in vitro condition. Results: It was found that ethyl acetate extract could scavenge both the oxidants at 500毺 g/mL with high percentage inhibition (88.26 暲0.35) of DPPH, and in the case of hydroxyl radicals the maximum percentage inhibition was 75.81 暲0.39, which were found to be greater in ethyl acetate extract than in positive controls such as Butylated hydroxytoluene (BHT) and ascorbic acid. The next higher inhibitory extract was found to be methanol. Conclusion: This shows that the plant Ageratum houstonianum may be a potent source of natural antioxidant
