The antioxidant activities are evaluated using a variety of in vitro and ex vivo systems, including DPPH free radical and superoxide radical scavenging assays, lipid peroxidation assay, hydroxyl radical-induced DNA strand scission assay. The accomplishment of this project would help determine the antioxidant components in the flower extracts of A. confusa. Accordingly, this study would benefit the potential development of indigenous tree species in different application areas.相思花抗氧化活性無定型自由基超氧自由基捕捉試驗Acacia confuse flowerantioxidant activitiesDPPH free radicalsuperoxide radical scavenging
