摘要：Reactive oxygen species (ROS) are highly reactive molecules due to their unpaired electron. They have been suspected as one of the major tissue damage inducers in biological metabolic systems. Antioxidant enzymes. such as catalase and superoxide dismutase,could not repair all the oxidative damages resulting from those excessive toxic ROS. It is,therefore,urgent to develop effective antioxidants to relieve from the oxida- tive damages. In this study antioxidative effects were investigated by using two flavonoids such as quercetin and naringenin and a flavonoid - rich extract,Ginkgo biloba extract in combination with paraquat that is known as a strong generator of oxygen radicals,.
