Abstract: The actions of Buckwheat honey, Chinese wolfberry honey, longan honey, loquat honey and Chinese date honey on Cu2+-induced oxidative modification of lipoproteins in human serum were determined. The results demonstrated that all tested honeys could delay and inhibit Cu2+-induced oxidative modification of lipoproteins in serum. Buckwheat honey has been found to show highest antioxidant than other honeys. The significant correlation between total phenolic content and antioxidant activity of the honeys (p<0.001, R2=0.9179) was found when the content of the tested honeys was 0.1 g/L.

Key words: honey, human serum, lipoprotein, antioxidant
