摘要:

通过HPLC-DPPH 和清除DPPH 自由基实验研究枣花蜜中对DPPH 自由基具有清除作用的活性成分,并测定已知活性成分的含量。结果表明:枣花蜜中存在12 种对DPPH 自由基有清除作用的活性成分,其中4 种是已知化合物——咖啡酸、对香豆酸、山奈酚和柚皮素,其含量在48.8~741.3μg/100g,各成分对DPPH 自由基的清除能力存在明显差异,其差异与分子结构密切相关。

Abstract:

The bioactive components in date honey having the ability to scavenge DPPH free radicals were quanlitatively and quantitatively analyzed by HPLC-DPPH. In total, 12 DPPH free radical scavenging components were found in date honey, and 4 of them were identified as caffeic acid, p-coumaric acid, naringenin and kaempferol. The contents of these components were in the range of 48.8 to 741.3 μg/100 g honey. The scavenging capacities of these bioactive components exhibited an obvious difference, which was highly correlated with the molecular structures of bioactive components.

Key words: date honey, bioactive components, scavenging effect on DPPH free radicals, molecular structure
