摘　　要：研究了花色苷清除DPPH.的能力,并用荧光化学发光法测定了花色苷对活性氧自由基(O2-·、·OH、H2O2)的清除作用。结果表明,该产品对DPPH·、O2-·、·OH、H2O2均具有清除作用,尤其对·OH的清除能力强于抗坏血酸,且清除作用与浓度呈量效关系。In this paper, the scavenging effect of anthocyanins extracted from red grape skin against DPPH·was studied and its scavenging activity against oxygen free radicals （O2^-·,·OH, H2O2） was determined by fluorescent chemiluminescence method . The results showed that remarkable scavenging effects against DPPH·, O2^-·,·OH and H2O2were detected, and it＇ s especially strong against·OH, even stronger than L-Ascorbic acid＇ s. Furthermore, scavenging activity and anthocyanins concentration showed a position of dose-response relationship.
