The antioxidant activity was measured by 2,2-Diphenyl-1-picryhydrazyl. One ml of ethanol solutions of appropriate concentration (0, 25, 50, 75 and 100 μl/100ml from 20 mM) of the FuFA was added to 1ml of 0.25 mM DPPH ethanol solution. Absorbance of each reaction mixture at 518 nm was measured from 0 to 120 min, against an ethanol blank, using a UV–VIS spectrophotometer
