| 摘 要： | 以红色老山芹、绿色老山芹、混合色老山芹的叶片和叶柄为试材,测定不同种类、不同部位老山芹的总酚、总黄酮含量及抗氧化能力,并分析功能活性与物质成分含量之间的相关性。结果表明:不同种类、不同部位老山芹的总黄酮含量、总酚含量大体上表现差异显著,3种老山芹叶片的总黄酮含量和总酚含量均显著高于叶柄;红色老山芹叶片醇提物的抗氧化能力最强,其次为混合色老山芹叶片,绿色老山芹叶柄最弱;各处理醇提物浓度在一定范围内与DPPH·自由基、OH·自由基、ABTS+自由基的清除能力均呈线性关系,醇提物浓度与抗氧化能力呈正相关;老山芹醇提物的抗氧化能力与叶片、叶柄总酚含量呈显著或极显著正相关,与总黄酮含量的相关性不显著。

| Abstract: | Taking the leave and petiole of red-colored，green-colored and secondary-colored Heracleum moellendorffii Hance as test material，this study measured the total phenols，total flavonoid content，antioxidant ability of different kinds and parts；and analyzed the correlation between functional activities and material composition contents．The result showed there were significant differences in total phenols and flavonoid content，and the total phenols and flavonoid content in leaves of above 3 kinds were significantly higher than that in their petioles．In the evaluation of antioxidant activity，the alcohol extracts of red leaf showed the highest antioxidant activity，followed by secondary-colored leaf，and that of the green-colored petiole was the weakest．The concentration of alcohol extracts exhibited linear relation with the scavenging ability of DPPH·free radicals，OH·free radicals and ABTS+ radicals．And there was positive correlation between the concentration of alcohol extracts and antioxidant ability．In conclusion，the antioxidant ability exhibited a significant or extreme significant positive relation with the total phenols content of leaf and petiole；and their correlation with total flavonoid content was non-significant． |
