Abstract: The ethanolic extract of Caralluma indica was screened for phytochemical analysis and in vitro antioxidant activity. The antioxidant activity screened through DPPH, total antioxidant assay, super oxide metal chelating, iron reducing power activity and nitric oxide scavenging activity at different concentrations and ascorbic acid as a standard antioxidant. Phytochemical analysis of various extract (Aqueous, Methanol, Ethanol and Ether) showed that the presence of rich source of active chemicals. Bioflavonoid content of Caralluma indica attributed the concentration dependent antioxidant activity. Overall antioxidant activity of Caralluma indica was found to be the strongest. The present study reveals that the Caralluma indica would exert several beneficial effects of virtue of their antioxidant activity and could be rendering useful as drug formulation.
