Rajeshwari Sahu* and Jyoti Saxena
ABSTRACT The present study was undertaken to compare the antioxidant activity of methanolic extract of rhizomes of conventional and nonconventional species of curcuma using DPPH free radical scavenging . The IC50 (The concentration of sample required to scavenge 50% of DPPH free radical) was calculated by plotting graph between % inhibition vs concentration. In our studying the conventional species Curcuma longa exhibited the highest antioxidant activity 69.8 ± 0.7 than non conventional species curcuma caesia 63.1± 0.2 and curcuma amada 44.1± 0.2 at 200μg/ml of the crude extracts respectively.
