Author(s): G. Sakthidevi and V. R. Mohan

The aim of this research work was to investigate the antioxidant potential of whole plant extracts of Polygala javana, Polygala chinensis and Polygala rosmarinifolia. The results of the present study revealed that the ethanol extract was found to be the highest DPPH radical scavenging activity when compared with standard ascorbic acid. The DPPH radical scavenging activities were 83.57%, 89.21%, 73.15% and 48.28%, respectively for Polygala javana, Polygala chinensis, Polygala rosmarinifolia and standard ascorbic acid. These results showed that whole plant extracts of Polygala species can be used as a significant source of natural antioxidant
