Study on the Scavenging Effects of Some Natural Products to Free Radicals by Chemiluminescence |
| |
Abstract: | The scavenging effects of some natural products to free radicals were detected by luminol H2O2 copper(II) chemiluminescence system. The results indicate that the scavenging activity to free radicals is soluble tea>water extract of tassels of maize>soybean isoflavonaoid>Vc>flower of robinia scholartre>acetone extract of peanut shell>alcohol extract of tassels of maize≈dioscorea opposita thunb. |
