| Studies on the Scavenging Effect of Catechin on Superoxide Anion Free Radical and its Self-oxidation |
|
|
| Abstract: |
| The scavenging effect of catechin on superoxide anio n free radical was determined by the method of nitro blue terrazolium photochemi cal reduction. The optimum assay wavelength of its self-oxidation was establishe d，and the effect of its concentration and solution pH on self-oxidation was di scussed. |
| Key words: Catechin Self-oxidation Superoxide anion free radical |
