Introduction: Non-enzymatic glycosylation of proteins which is the major cause of diabetic complications, cardiovascular diseases retinopathy, nephropathy and neuropathy can effectively be inhibted by antioxidants.
Materials and Method: The antioxidant effects of several flavonoids, such as rutin, kaempferol, quercetin, apigenin, naringin, morin and biochanin A were studied  on glycosylation of insulin, hemoglobin and albuminin In-vitro.
Optimal glucose concentration as well as incubation time were determined and inhibition percentage of the proteins were measured at three different concentrations (0.5,5 and 10 μg/ml) using spectrophotometric method.
Results: This study showed that biochanin A has potent antioxicant effects as it inhibits glycosylation of hemoglobin insulin and albumin by 100%, 60% and 100% respectively.Apigenin is also inhibits albumin glycosylation by 100%.
Conclusion: As potent antioxidant effects are induced by flavenoedes, preventive effects of some plants containing the flavonoids on diabetic complication is expected.
