To study the antioxidant potency of hydro alcoholic extract of Cassia uniflora. Hydro alcoholic leaf extracts of the plants was studied for its Free radical scavenging activity against DPPH, ABST and Superoxide ion. Hydro alcoholic crude extracts of leaves of Cassia uniflora at concentrations of 10, 25, and 50?g/ml were studied against DPPH, ABST and Superoxide ion to know their antioxidant potential. Cassia uniflora leaf hydro alcoholic extract possessed an IC50 value 26.32 ?g/ml in DPPH radical scavenging assay on compare to standard Vitamin C (3.59?g/ml), in ABST radical scavenging assay 8.76 ?g/ml and standard vitamin C (2.32 ?g/ml) and in Super oxide ion scavenging recorded as 45.84 ?g/ml and for standard gallic acid was found to 0.61 ?g/ml. The crude extracts showing better activity against DPPH ABST and Superoxide ion. Hence, can be recommended for potential usage as an antioxidant agent in pharmaceutical and nutraceutical industries.
