| 摘 要： | 为了研究邻苯二酚对红香椿叶和绿香椿叶营养品质和抗氧化性的影响,分别对添加了0.5%邻苯二酚和1.0%邻苯二酚的香椿叶进行青贮。结果表明,香椿叶青贮蛋白组分保存良好,真蛋白含量保存稳定,非蛋白氮和氨态氮含量较低,抗氧化性略有降低,但保持在较高水平。与CK相比,邻苯二酚显著提高了青贮自由基1,1-二苯基-2-三硝基苯肼(DPPH)清除活性和铁离子还原力(FRAP)活性(P<0.05)。经Pearson相关分析,香椿叶的抗氧化性与总黄酮含量呈正相关关系(P<0.01)。青贮良好地保存了香椿叶的营养品质和抗氧化性。在邻苯二酚的作用下,香椿叶青贮的抗氧化性得到了提高,香椿叶青贮具有较高的营养价值和抗氧化性。

| Abstract: | This study investigated the effect of catechol on the nutritional quality and antioxidant activity of ensiled Toona sinensis leaves （TSL）. The results showed that the protein fraction of TSL silages was preserved well， with the non-protein nitrogen and ammonia concentrations maintained at a low level. Antioxidant activity was decreased slightly by catechol but remained high. Compared with the CK treatment， catechol significantly increased （P<0.05） 1，1-diphenyl-2-picrylhydrazyl （DPPH） free radical scavenging activity and ferric-reducing antioxidant potential （FRAP）. Pearson correlation analysis showed that the antioxidant activity of TSL silage was positively correlated with the total flavonoid content （P<0.01）. The nutritional quality and antioxidant activity of TSL were well preserved by ensiling. With the addition of catechol， the antioxidant activity of TSL silage was significantly improved. TSL silage had high nutritional value and antioxidant activity. |
