Radical scavenging activity of mango powders was determined
following Brand-Williams, Cuvelier, and Berset (1995).
Briefly, one part of stock solution of 2,2-Diphenyl-1-
picrylhydrazyl or DPPH (0.24 g/100 mL methanol) was diluted
with ten parts methanol-80 to get working solution having
absorbance of 1.1 0.02 at 515 nm. Blank, standard or samples
(0.6 mL) and 3.0 mL of DPPH working solution were mixed, kept
in dark for 20 min and absorbance was recorded at 515 nm.
Standard curve was prepared to calculate DPPH activity using
