【摘要】 分析了中熟品种久保和京玉、晚熟品种绿化九号与冈山白4种桃果实的酚类活性成分,并对其进行了抗氧化功能的研究。经高效液相色谱及比色分析结果表明,4种桃果实总酚的含量具有显著性差异;黄烷醇的含量均在10~14μg/g;中熟品种的类黄酮含量要比晚熟品种的含量高。抗氧化实验结果表明,4种桃果实酚类提取液均具有很强的抗氧化活性,且对.OH、O2.-有较明显的清除效果,但它们对R.的清除效果较差。更多还原

【Abstract】 Phenolic active ingredients in Okubo,Jingyu,Green 9^#,Hakuto and their antioxidative activities were analyzed.The results showed that the great quantitative differences in the contents of total phenolics and the contents of flavanol were 0.010～0.014 mg/g in four peach varieties.The contents of flavonid in Okubo,Jingyu were higher than that of Green 9^#,Hakuto.In addition to phenolic ,the extracts of four kinds of peach had powerful antioxidant activities and significantly scavenging effects on（）^·OH and O₂^·-,but were not significant on R^·.更多还原
