Free Radical Scavenging Assay

The antioxidant activity of four honey samples from different floral sources (Acacia, Coriander, Sider and Palm) were evaluated with three different assays; DPPH free radical scavenging assay, superoxide anion generated in xanthine–xanthine oxidase (XOD) system and low density lipoprotein (LDL) peroxidation assay. The dark Palm and Sider honeys had the highest antioxidant activity in the DPPH assay. But all the honey samples exhibited more or less the same highly significant antioxidant activity within the concentration of 1mg honey/1 ml in XOD system and LDL peroxidation assays. The chemical composition of these samples was investigated by GC/MS and HPLC analysis, 11 compounds being new to honey. The GC/MS revealed the presence of 90 compounds, mainly aliphatic acids (37 compounds), which represent 54.73, 8.72, 22.87 and 64.10% and phenolic acids (15 compound) 2.3, 1.02, 2.07 and 11.68% for Acacia, Coriander, Sider and Palm honeys. In HPLC analysis, 19 flavonoids were identified. Coriander and Sider honeys were characterized by the presence of large amounts of flavonoids.

Mediated Oxidation

The oxidative modification of low-density lipoprotein (LDL) can be induced by various active species by different mechanisms. Vitamin E and other radical-scavenging antioxidants can inhibit the free radical-mediated oxidation of LDL, but they are not effective against LDL oxidation induced by non-radical mechanisms.
