为进一步综合利用佛手花，该研究测定了其对DPPH自由基和羟自由基的清除能力，并与对照槲皮素、山奈酚、咖啡酸、芦丁、没食子酸和对香豆酸进行比较。结果表明：各物质清除DPPH自由基的能力为：对香豆酸＜佛手花提取物＜香草酸＜芦丁＜咖啡酸＜没食子酸。清除羟自由基的能力为：芦丁＜咖啡酸＜佛手花提取物＜山奈酚＜槲皮素。说明佛手花提取物具有很好的抗氧化活性，是一种良好的天然抗氧化剂。
為進一步綜閤利用彿手花，該研究測定瞭其對DPPH自由基和羥自由基的清除能力，併與對照槲皮素、山奈酚、咖啡痠、蘆丁、沒食子痠和對香豆痠進行比較。結果錶明：各物質清除DPPH自由基的能力為：對香豆痠＜彿手花提取物＜香草痠＜蘆丁＜咖啡痠＜沒食子痠。清除羥自由基的能力為：蘆丁＜咖啡痠＜彿手花提取物＜山奈酚＜槲皮素。說明彿手花提取物具有很好的抗氧化活性，是一種良好的天然抗氧化劑。
위진일보종합이용불수화，해연구측정료기대DPPH자유기화간자유기적청제능력，병여대조곡피소、산내분、가배산、호정、몰식자산화대향두산진행비교。결과표명：각물질청제DPPH자유기적능력위：대향두산＜불수화제취물＜향초산＜호정＜가배산＜몰식자산。청제간자유기적능력위：호정＜가배산＜불수화제취물＜산내분＜곡피소。설명불수화제취물구유흔호적항양화활성，시일충량호적천연항양화제。
In order to further comprehensive utilization of flower of Citrus medica ,the scavenging activities of DPPH free radical and hydroxyl radical were determined ,and they were compared with quercetin ,kaempferol , caffeic acid ,rutin ,gallic acid and p-coumaric acid .The results showed that the scavenging activities of DPPH free radical was p-coumaric acid< extract from flower of Citrus medica< vanillic acid< rutin< caffeic acid<gallic acid ,the scavenging activities of hydroxyl radical was rutin <caffeic acid<extract from flower of Citrus medica<kaempferol<quercetin .It indicated that extract from flower of Citrus medica had good antioxidant ac-tivity and could be a good natural antioxidant .
