| 摘 要： | 以胆木叶为原料,通过不同极性溶剂依次萃取50%醇提取物,分别得到石油醚萃取物(PEE)、氯仿萃取物(CE)、乙酸乙酯萃取物(EAE)、正丁醇萃取物(BE)和水萃取物(WE),它们的收率依次为0.62%、3.90%、0.68%、1.78%和6.06%.采用过氧化氢体系、超氧阴离子(O-2·)体系、羟基自由基体系(·OH)和Oyaizu法,以Vc为阳性对照,进行5个不同萃取部分抗氧化活性的测定和比较.结果表明,5种萃取部分均具有一定的抗氧化活性,随着浓度的增加而提高;且在不同的自由基产生体系中,其抗氧化活性强弱不尽相同.在过氧化氢体系中,对H2O2的清除能力强弱顺序依次为Vc>BE>CE>EAE>PEE>WE;在超氧阴离子体系中,对O-2·抗氧化活性强弱顺序依次为Vc>EAE>BE>PEE>WE>CE,在羟基自由基体系中,对·OH抗氧化活性强弱顺序依次为Vc>BE>CE>EAE>PEE>WE;而其还原能力强弱顺序依次为 BE>EAE>WE>CE>PEE. |
