SCREENING OF DIFFERENT PARTS OF THE PLANT PANDANUS ODORUS FOR ITS ANTIOXIDANT ACTIVITY

The present study was undertaken to explore the antioxidant potential of different parts of the plant Pandanus odorus that is believed to be useful in the treatment of diabetes.1,1-diphenyl-2-picrylhydrazyl (DPPH) was used in determining the free radical scavenging activity and ascorbic acid was used as standard. All the fractions of both leaves and root showed potential antioxidant activity. In case of leaves the chloroform fraction showed highest radical scavenging activity with IC 50 value of 1.66 µg/ ml followed by petroleum ether and ethyl acetate fraction having IC 50 value of 4.69 µg/ ml and 26.21 µg/ ml respectively. In case of root, the petroleum ether fraction showed highest radical scavenging activity with IC 50 value of 1.42µg/ ml followed by ethyl acetate and chloroform fraction having IC 50 value of 3.76 µg/ ml and 7.01 µg/ ml respectively.
