The present investigation deals with the extraction, phytochemical constituent analysis and antioxidant activity analysis of Calatropis gigantea extracts. It was observed that the yields of extraction depend on nature of solvent. It was found that the water and ethanol are the best possible solvents for having higher yields compared to other solvents chosen of varied polarities. Polyphenol content determination indicates that the water and methanol extracts were found to have highest percent of polyphenols than other extracts. The Flavonoid estimation of the extracts indicate that ethanol extract possess highest amount of flavonoids among all the extracts of different solvents. The DPPH activity analysis indicates that ethanol extract evidenced to have potential antioxidant activity among all extracts of different solvents. This is probably due to the significantly high biologically potent phytochemicals compared to other extracts. This investigation points out that the Calatropis gigantea contains significant amounts of antioxidant compounds such as polyphenols and flavonoids. Consequently various extracts showed potential antioxidant activity. Hence it is worth to consider Calatropis gigantea for further exploration in utilizing it as rich antioxidant.
