From: The effect of pomegranate fresh juice versus pomegranate seed powder on metabolic indices, lipid profile, inflammatory biomarkers, and the histopathology of pancreatic islets of Langerhans in streptozotocin-nicotinamide induced type 2 diabetic Sprague–Dawley rats

Samples Inhibition percentages in concentration 200 μg/mL IC50 values (μg/mL)
Ascorbic acid 81.31 ± 0.86% 21.05 ± 8.05
Pomegranate Juice 86.89 ± 0.26%** 65.12 ± 1.44**
Pomegranate Seed 53.98 ± 1.25%*** 159.90 ± 6.24***
  1. The values are expressed as means ± S.E.M. for 3 experiments; *p˂0.01, **p˂0.001 are considered as significant compared to standard ascorbic acid
