In evaluation, methanol extract of the root powder was prepared and screened for in-vitro antioxidant activities by 1, 1-diphenyl-2- picrylhydrazyl (DPPH) free radical scavenging activity and by reducing power assay method. The results of both the methods were compared with a natural antioxidant ascorbic acid (vitamin C) as a standard. . In DPPH free radical scavenging assay, IC50 values of methanol root extract and Ascorbic acid was found to be 50.1µg and 22.0 µg/ml respectively. The results concluded that the extract has potential source of antioxidants of natural origin.
Key words: Antioxidant, Capparis grandiflora, DPPH, free radical, reducing power.
