DPPH radical scavenging activity of fruit peel and seed extracts were determined as described by Brand-Williams et al. (1995) with a slight modification. The DPPH radical (0.004%) was prepared by dissolving DPPH with 95% ethanol. The extracts with various amounts were added to 1 mL of the DPPH radical solution and the final volume of 2.50 mL was adjusted with 95% ethanol. After 30 min, the absorbance was measured at 517 nm. The inhibitory effect of the extract was expressed as extract concentration causing 50% loss of enzyme activity (IC50).
