摘要
研究海南红厚壳果实正己烷、无水乙醇、三氯甲烷、乙酸乙酯4种不同溶剂粗提液的抗氧化活性,筛选确定乙醇提取物具有较好的抗氧化活性。进一步测定海南红厚壳果实乙醇提取物清除DPPH自由基能力、还原力、抗脂质体过氧化活性、过氧化氢清除能力,并与抗氧化剂BHT和VC进行比较,对海南红厚壳果实抗氧化能力进行评价。结果表明海南红厚壳果实的乙醇粗提液具有较好的抗氧化活性,在某些抗氧化性能方面优于BHT,但总体不如强抗氧化剂VC。
Extraction from Calophyllum inophyllum L.fruit by different solvents such as hexane,ethanol,chloroform and ethyl acetate had different antioxidant activities.It has been proved that ethanol extraction showed stronger antioxidant activities.Further compared with Butylated Hydroxytoluene（BHT） and Vitamine C（VC）,the ethanol extraction also showed better antioxidant activities in DPPH free radical scavenging activity,reducing power,antioxidant activity in liposome model system and scavenging H2O2 activities.The antioxidant activity results showed that ethanol crude extract from Calophyllum inophyllum L.fruit was superior to BHT in some aspects,but overall not as strong as VC
