Antioxidant activity has been assessed by in vitro method for phytochemical fraction of plant; viz. water extracts of root, stem and flower of Taraxacum officinale plant. This investigation was under taken to evaluate water extracts of taraxacum officinale plant for possible antioxidants potential. Antiradical activity of all extracts was measured by 1, 1, diphenyl-2, picrylhydrazyl (DPPH) assay and was compared to ascorbic acid and Ferric reducing power (FRAP) of the extract. In the present study two in vitro models were used for evaluation of antioxidant activity. The first one method was for direct measurement of reducing power and the other one for radical scavenging activity. The present study revealed the Taraxacum officinale has significant radical scavenging activity.
