Abstract

The scavenging ability on ROS of anthocyanins from blueberry was evaluated by chemiluminescence in models for generation of superoxide anions ,hydroxyal radicals and peroxide. The results showed that the anthocyanins from blueberry could scavenge superoxide anions ,hydroxyal radicals and peroxide.The scavenging ability was also related with the concentration of anthocyanins. Anthocyanins were more stronger ability on scavenging superoxide anions and hydroxyal radicals than ascorbic acids. Anthocyanins were less stronger ability on scavenging peroxide than ascorbic acids. IC50 of anthocyanins of blueberry on scavenging superoxide anions,hydroxyal radicals and peroxide were 81.36,7.21,80.43 mg/L.
