Abstract:
Antioxidant activity of the ethanol extract of Erigeron breviscapus (EEEB) were studied by using neuron oxidative injury model induced by superoxide radical. EEEB at the dose of 10-140 mug/ml reduced significantly the lipid peroxidation levels and lactic dehydrogenase (LDH) release from neuron exposed to superoxide radical (generated by xanthine and xanthine oxidase). These results suggest that neuroprotective actions of EEEB may be due to its antioxidant or radical scavenging activity.
