3个品种芒果果核乙醇提取物抗氧化活性

Antioxidant Activities of Ethanol Extracts from Three Varieties of Mango Seeds

对3个品种芒果果核提取物抗氧化活性进行研究。结果表明,3个品种中"台农"芒果核总酚含量最高((9.04±0.03)mg/g),"金煌"((8.22±0.10)mg/g)次之,"贵妃"((7.25±0.10)mg/g)最少。3个芒果品种芒果核乙醇提取物均具有一定的清除DPPH自由基、清除ABTS+.、Fe3+还原力、抗脂质氧化、Fe2+络合能力和清除羟自由基的能力。其中"台农"果核提取物抗氧化能力较强,并且清除率和质量浓度间存在剂量依赖关系。

Ethanol extracts from three varieties（Tainong,,Jinhuang,and Guifei,） of mango seeds were evaluated for their antioxidant activities.The results showed that Tainong,mango seeds had the highest content of total phenolics,followed by Jinhuang,and Guifei,.Each of these extracts had strong abilities to scavenge DPPH,ABTS and hydroxyl free radicals,reduce to iron（III）,chelate iron（II） and inhibit lipid peroxidation,and among them,Tainong,mango seeds revealed stronger free radical scavenging ability in a dose-dependant manner.
