采用化学发光法测定了光果甘草( Glycyrrhiza glabra L.) 与乌拉尔甘草( G. uralensis Fisch .) 中总黄酮和总皂甙
对 3 种重要活性氧( O^{2 — .}、·OH 和H2O2) 的清除能力, 发现它们对 3 种活性氧均有很强的清除能力, 其中光果甘草对
活性氧的清除能力超过乌拉尔甘草;黄酮类化合物对3 种活性氧的清除能力强于皂甙类化合物。 因此, 若以清除
活性氧为应用目标, 应尽量使用光果甘草。
 

The abilities of scavenging reactive oxygen species ROS ( O^{2 .}  ,·OH and H2O2 ) of flavonoids and
total saponins in roots of Glycyrrhiza glabra L .and G.uralensis Fisch .were analysed by chemluminescence.The results showed that both of them have significant effects on ROS, moreover G. glabra has a stronger effect and the flavonoids′effect is stronger than that of total saponins .G. glabra should be possible used if the target is to scaveng ROS .
