Plants represent the best and most extensively studied source of natural antioxidants. The present study investigated the antioxidant and anti-glycation properties of different concentrations of essential oils obtained from fruits and branchlets of Juniperus oblonga M. Bieb., Cupressaceae, using different assays. The essential oils were obtained by steam distillation of the branchlets of male tree (BMT), branchlets of female tree (BFT) and fruits of J. oblonga. Compositional analysis of oils was performed using a gas chromatography-mass method. Antioxidant activity was assessed using linoleic acid peroxidation, peroxyl radical mediated hemolysis of red blood cells (RBC) and low-density lipoprotein (LDL) oxidation assays. Anti-glycation properties of oils were evaluated using hemoglobin and insulin glycation assays. Seventeen, eighteen and fifteen compounds were identified in the BMT, BFT and fruit oil, which represented 82.51, 55.69 and 96.89 of the total oils, respectively. α-Pinene was the major component of all three oils. All three oils possessed antioxidant effects against LDL oxidation, linoleic acid peroxidation and peroxyl radical mediated RBC hemolysis. Anti-glycation activities against hemoglobin and insulin glycation were also observed from all tested oils. Overall, there was no unique pattern of dose-dependence for the antioxidant properties of oils in different employed systems. The findings of this study suggest that essential oils from fruits and branchlets of J. oblonga possess antioxidant and anti-glycation properties. Therefore, these oils might be of therapeutic efficacy against diabetes and cardiovascular disease.
