| 中文摘要: |
| 对元宝枫翅果的果翅、种皮、仁粕中的总酚、缩合单宁和总黄酮3种活性成分含量进行测定，并应用FRAP法、DPPH自由基清除能力和ABTS+·清除能力等方法对翅果提取物的体外抗氧化能力进行评价。结果表明，种皮中3种活性成分含量最高，其总酚、缩合单宁和总黄酮含量分别为342.83 mgGAE/g、847.45 mgCE/g、57.66 mgRT/g，仁粕中含量最低；翅果不同部位提取物的FRAP抗氧化能力、对DPPH自由基和ABTS+·的清除能力均存在显著性差异，提取物的体外抗氧化能力依次表现为：种皮>果翅>仁粕；相关性分析发现，翅果不同部位提取物中总酚和缩合单宁含量与抗氧化能力呈显著正相关。 |
| 英文摘要: |
| The contents of total phenolics, condensed tannins and total flavonoids in fruit wing, seed coat and seed kernel meal of Acer truncatum Bunge. were analyzed, and the vitro antioxidant capacity of the samara extract were evaluated through FRAP method, DPPH radical scavenging ability and ABTS+ · scavenging capacity. The results indicated that the contents of three bioactive components in the seed coat were the highest. The contents of total phenolics, condensed tannins and total flavonoids in seed coat were 342.83 mgGAE/g, 847.45 mgCE/g and 5766 mgRT/g respectively. The contents of three bioactive components in seed kernel meal were the lowest. There were significant differences in different parts of samara in the FRAP antioxidant capacity and the scavenging activities of DPPH free radical and ABTS+·, and the sequence of antioxidative capacity from high to low was:seed coat, fruit wing, seed kernel meal. In addition, the antioxidative capacity was positively correlated with the contents of total phenolics and condensed tannins in different parts of samara. |
