The effect of Cerasus avium stalk extract on albumin glycation reaction

Non-enzymatic glycosylation of proteins is the major cause of diabetic complications. The inhibition of glycation process can reduce complications of diabetes. In the Iranian traditional medicine, the decoction (boiled extraction) of Cerasus avium stalk is used as a hypoglycemic agent. The aim of this study was to investigate the in vitro inhibitory effects of decoction and ethanolic and aqueous extracts of Cerasus avium stalk on albumin glycation reaction. In this experimental study, first, the ethanolic, aqueous and decoction extracts of Cerasus avium stalk were prepared. Then, different concentrations of these extracts were prepared and added to albumin and glucose solutions. Finally, compared to control group that was not treated with any extracts, the albumin glycation rate in the groups treated with various concentrations of extracts was evaluated using TBA (thio-barbituric acid) method. The results showed that compared to control group, decoction of Cerasus avium stalk in the concentrations of 20, 10 and 2 mg/dl could reduce albumin glycation to 85.10±1.55, 72.35±1.75 and 51.25±1.22 %, respectively (P>0.001). Moreover, in the concentration of 20 mg/dl, the inhibitory effect of decoction of Cerasus avium stalk on the albumin glycation reaction was higher than those of aqueous (P=0.021) and ethanolic (P=0.009) extracts. The findings showed that the extracs of Cerasus avium stalk, in particular in the decoction form, could significantly reduce the rate of albumin glycation; therefore, it can be used for decreasing diabetes mellitus complications.
