Examination the antioxidant potentials and antidiabetic properties of phenolic extracts of some Iranian honeys

Introduction: In most ancient cultures, honey has been used for both nutritional and medical purposes. Objectives: this research, phenolic extracts of four Iranian honeys were evaluated to determine the antioxidant potentials using DPPH (2,2-diphenyl-1-picrylhydrazyl) radical scavenging, nitric oxide (NO) scavenging reducing power by ferric activity plasma (FRAP) method. Additionally, anti-diabetic properties determination ?-amylase ?-glucosidase inhibition. Patients Methods: Besides, potential was ferric-reducing Moreover, flavonoid contents performed. inhibition evaluated. Results: With considering potentials, Gavan (Astragalus) sample showed greatest (3817±1.52 mg GAE/100 g), (3.1±0.005 QE/100 (IC 50 = 2±0.003 mg/mL). Bahareh had highest NO (IC50=0.0403±0.0009 mg/mL) Meymand possessed FRAP method =0.0018±0.000003 The maximum shown in extract (46±0.1%). After sugar isolation, Zataria (54±0.6%) mode noncompetitive honey. Whole (23±0.1%) presented (31.2±0.1%). Conclusion: Honey samples retardation ?-glucosidase.
