The scavenging ability of ABMPs on ABTS free radicals was shown in Fig. 3. The scavenging power of ABMP-V and ABMP-A was slightly lower than ABMP-F at the same concentration.
These results suggested that ABMP-F had the strongest scavenging power on ABTS radicals in contrast to the weakest power of ABMP-A.
There was no significant difference (P > 0.05) between ABMP-V and ABMP-A on ABTS free radical scavenging.
Moreover, ABMPs exhibited higher than 50% scavenging ABTS radical capacity when the concentration reached 0.3 mg/mL. The results indicated that ABMP had strong scavenging power on ABTS radicals and could be explored as a potential ABTS scavenger.
