摘要
通过DPPH·/O2-·自由基清除体系,研究了首乌藤不同黄酮组分的体外抗氧化活性,实验结果表明,首乌藤不同黄酮组分对·OH、DPPH·都具有一定的清除能力,首乌藤黄酮是一种良好的抗氧化剂。
The antioxidant activities of different polarity flavonoids from extract of Caulis Polygoni Multiflori were investigated by 1, 1-diphenyl-2-picrylhydrazyl (DPPH.)/peroxide anion. The different polarity flavonoids from extract of Caulis Polygoni Multiflori showed effective reducing power and scavenging activity against free radicals, such as DPPH., peroxide anion. Different polarity flavonoids from extract of Caulis Polygoni Multiflori has obvious antioxidant activities in vitro.
