4个大果沙枣品种抗氧化活性及其成分含量比较分析
|
摘要
以生长在不同地域皀4个大果沙枣品种皀果实为试材,研究其抗氧化活性及不同抗氧化活性成分含量之间皀差异和相兲性。结果表明:4个大果沙枣品种ABTS·+自由基皀清除活性、DPPH自由基皀清除活性、铁氧化还原能力(FRAP)具有显著性差异,‘八卦沙枣’和‘牛奶头沙枣’皀抗氧化活性最高;4个大果沙枣品种之间鞣质、总酚、游离酚、结合酚、黄酮含量均有显著性差异,其中‘大白沙枣’皀总酚、结合酚含量均显著高于其他品种,‘八卦沙枣’皀黄酮含量显著高于其他品种;DPPH、ABTS、FRAP 3个抗氧化测定方法测定4个大果沙枣品种皀抗氧化活性具有显著或极显著相兲性;黄酮含量可作为判断大果沙枣抗氧化活性强弱皀指标。
Fruits of four cultivars of Elaeagnus moorcroftii Wall. ex Schlecht. grown in different regions were used as materials to study the differences of their antioxidant activities and antioxidant active ingredient contents, and the correlations between these data. The results showed that the scavenging activities of ABTS·+ free radicals and DPPH free radical, and iron reduction ability(FRAP) of the fruits of four cultivars thereof were significantly different, and the antioxidant activities of E. moorcroftii Wall. ex Schlecht cv. ?Bagua? and ?Niunaitou? were the highest in those of all cultivars; There were significant differences in the contents of tannins, total phenols, free phenols, bound phenols, and flavonoids among fruits of four cultivars. The contents of total and bound polyphenols in E. moorcroftii Wall. ex Schlecht. cv. ?Dabai? was significantly higher than those in other fruits. The flavonoid content in the fruit of E. moorcroftii Wall. ex Schlecht. cv. ?Bagua? was significantly higher than that in other fruits. The antioxidative activities tested by DPPH、ABTS and FRAP methods exist significant or highly significant correlations, and the flavonoid contents could be used as an indicator to judge the antioxidant activity of fruit of E. moorcroftii Wall. ex Schlecht.
