based on the reduction of methanolic DPPH solution in
the presence of hydrogen-donating antioxidant due to the
formation of non-radical form DPPH-H (Duan, Zhang, Li,
& Wang, 2006) by the reaction. DPPH is one of the
compounds that possess a proton free radical and shows
maximum absorption at 517 nm. When DPPH encounters
proton radical scavengers, its purple colour faded rapidly.
This assay determines the scavenging of stable
radical species of DPPH by antioxidants. The radicalscavenging
activity is ranged between 73.90% and 85.95%
gallic acid equivalents and was found high in wines of
Himami pasand, followed by Neelam and Banginapalli
(Figure 3).
