    Abstract: 在本實驗中,我們以中藥知母作為抗氧化活性試驗篩選,並比較不同萃取溶劑下,抗氧化活性的差異,抗氧化活性試驗的評估方法包括清除α,α-diphenyl-β-picrylhydrazyl(DPPH)自由基、螯合亞鐵能力(Chelating activity on ferrous ion)與還原能力( Reducing power test )測定,並配合總多酚類含量( Total phenolic compound content ) 測定。經實驗結果顯示知母水萃取物具有最明顯的清除DPPH 自由基能力,其IC50 值為0.11±0.01mg/ml,並具有最高的總多酚含量,其值為12.56mg GA/g。因此,知母水萃取物具有優異的抗氧化能力,具有在保健食品和化妝品工業上應用與開發之潛力。
