摘　　要：天然药物中含有多种抗氧化的活性物质,其用作抗氧化剂较化学合成药品而言具有无毒、副作用小等优点,但有关抗氧化的机理仍处于探索阶段。为了进一步从细胞分子水平揭示三叶委陵菜可能的抗氧化机理,本文用化学反应的方法分别测定湖北恩施、麻城两地三叶委陵菜不同溶剂萃取部位的体外抗氧化活性。结果表明,恩施三叶委陵菜抗氧化活测定略强于麻城三叶委陵菜,且正丁醇提取部位体外抗氧化活性最强。Natural medicine contains a variety of oxidation resistance materials,compared to chemical synthetic drugs,it has the advantages of non-toxic,minimal sideeffect etc,but the antioxidant mechanism is still in the exploratory stage.In order to reveal the possible antioxidation mechanism of the Potentilla freyniana from the cell molecular,the method of chemical reaction was used to determine the antioxidant activity of different solvent extraction of the Potentilla freyniana.The results showed that the antioxidant activity of the Potentilla freynianafrom Enshi was stronger than that from Macheng,the antioxidant activity of n-butanol extract position was the strongest.
