	%X The potential of antioxidant activities of the plant
extract Gynura procumbens, Achyranthes aspera and Polygenum
tomentosum were studied by using 1, 1-diphenyl-2-picrylhydrazyl
(DPPH) .Antioxidant activity was qualitatively and quantitatively
determined. In this analysis , Ascorbic acid (Vitamin C) was used as
the standard .The antioxidant activities were observed all three plant
extracts and the EC50 values of G procumbens A.aspera and
P.tomemtosum were 13.7 μg /ml,14.37 μg /ml and 14.35 μg /ml.
Among these plants, G.procumbens is more potent antioxidant
activity then others. Antitumor activities were found with A.aspera
(s2) extracts in the dose of 100ppm in carrot disks and G.procumbens
(s1) and P.tomentosum (s3) in the dose of 1000 ppm. Therefore, these
herbal plants are used in traditional medicines.
