中药对超氧阴离子自由基清除率的测定
Determination the Removing Rate of Superoxide Anion Radical by Traditional Chinese Medicine
摘要
Abstract
A new method for the determination the removing rate of superoxide anion radical（O2-.） was established.with the pyrogallol-AzureⅠsystem was established.The method is based on the reaction of pyrogallol self-oxidation in basic solution to form O2-.that it can quickly oxidate azure Ⅰdecoloration,and traditional Chinese medicine extract can inhibit the oxidation of azureⅠby O2-..The optimal experimental conditions for the determination system was pH 9.0,azureⅠ5.0 mL,pyrogallol 0.8 mL,reaction time 9 min.The removing rate of six traditional Chinese medicine extract for O2-.were determined,the results showed the sequence of removing rates with plantain seedmedlarszechwan lovage rhizomeangelicatuckahoeblackberrylily rhizome.关键词
