基本解釋

Scavenging activities of seven natural flavonoids from elsholtzia bodinieri vaniot and artemisia ordosica kraschen for superoxide anion radicals was studied by single-sweep oscillopolarography.
摘要用單掃描示波極譜法研究了從東紫蘇和黑沙蒿中分離出的七種黃酮類化合物對超氧陰離子自由基的清除作用。
Methods: The electron spin resonance(ESR)was used to observe the scavenging effect on the superoxide anion radical(O2.
方法:采用電子自旋共振技術(ESR)分別檢測大黃中主要成分對O2.;-的清除作用。結果:大黃中主要成分對O2
IC50 of grape polyphenols on scavenging DPPH radical, superoxide anion radical and hydroxyl radical were 1.
