Antioxidant activity of EUP1, EUP2 and EUP3. A DPPH radical scavenging activity. B IC50 of DPPH radical scavenging activity. C OH radical scavenging activity. D IC50 of OH radical scavenging activity. The standard error of the mean is denoted by a capped bar at the top of each column. Different letters indicate significant difference between different components by Tukey’s test (p < 0.05)
