This study aimed to look for phytochemicals in 60 % methanolic, 60 % ethanolic and aqueous extracts of Achyranthes aspera leaves and Mesua ferrea flowers and evaluate their antioxidant potential using free radical scavenging activity (DPPH). The dried powders of the botanicals were also subjected to the study. The flavonoids, phenols, tannins and carbohydrates were identified in the methanol and aqueous extracts of A. aspera and also in methanol and ethanol extracts of M. ferrea. The saponins were only present in the dried powder and ethanol extract of A. aspera. The presence of alkaloids was only seen in the dried powders. The mean IC50 DPPH values for the dried powders and the extracts of ethanol, methanol and aqueous extracts of A aspera were found to be 65.67, 58.33, 21.20 and 36.41 µg/ml, respectively. While comparing with the DPPH activity on the dried flowers of M. ferrea it exhibited significantly lower activity than the A. aspera. The findings of this experiment suggest that A. aspera has much more antioxidant activity than M. ferrea, and has greater therapeutic properties for humans that can be utilized by the food industry in substituting it with synthetic antioxidants.
