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
