用自旋捕捉技术研究了抗白内障中草药处方中各成分的水煎液及其片剂的水浸液清除羟自由基(·OH)的作用。发现它们对·OH 均有明显的清除作用,在反应系统中·OH 信号的猝灭与三种中草药和片剂的浓度有关。
Using spin-capture technology, the effects of aqueous extracts of various components of decoction and tablets on the scavenging of hydroxyl free radicals (·OH) were studied. They were found to have a clear scavenging effect on OH. The quenching of the OH signal in the reaction system was related to the concentration of the three Chinese herbs and tablets.
