In-vitro antioxidant activity of various extracts of the leaves of Capparis grandiflora Wall.Ex
Hook was determined by DPPH free radical scavenging assay. The Reducing power of extracts
was also determined. Ascorbic acid was used as standard and positive control for both the
analysis. The chloroform and ethanolic extracts of Capparis grandiflora showed very
significant DPPH (1,1-diphenyl-2-picryl-hydrazyl) radical scavenging activity compared to that
of standard antioxidant. The DPPH radical scavenging activity of the extract was increased with
the increasing concentration. In DPPH free radical scavenging assay, IC50 value of chloroform
and ethanol leaf extracts was found to be 39.2 �Ž�¼g/mL and 30.7 �Ž�¼g/mL respectively. The results
concluded that the extracts have a potential source of antioxidants of natural origin.
