Statistical Analysis
Three parallel experiments were performed to obtain the average value, which was determined using SPSS 23 statistical software and compared between groups using independent-sample t tests and a one-way analysis of variance method. Significant differences between groups were observed at the
P 0.05 level.
DPPH and ABTS Radical Scavenging Abilities of LPE
Figure 1 shows the dose-response relationship of DPPH and the ABTS radical scavenging ability of LPE. The ability of LPE to scavenge DPPH and ABTS radicals increased with increasing concentrations of LPE from 0 to 120 μg/mL. Moreover, the Vc positive control group had lower DPPH and ABTS radical scavenging abilities than LPE.
