EC50 values in different antioxidant assays and IC50 value in PPO inhibition activity of oriental melon peel extract and ascorbic acid

Samples EC50 1) Values IC50 2) Value
DPPH radical scavenging activity ABTS radical scavenging activity Copper chelating activity PPO inhibition activity
Oriental melon peel 0.26±0.013) 0.76±0.01 0.70±0.03 0.33±0.05
Ascorbicacid 0.01±0.00 0.10±0.01 0.20±0.00 0.01±0.00
EC50 value is the term half maximal effective concentration, %
IC50 value is the term half maximal inhibitory concentration, %
Each value represented mean±SD (n=3).
