Objective(s): Paraoxonase-1 (PON1), an HDL-associated enzyme, prevents lipoprotein oxidation. PON1 enzymatic activity has been shown to decrease in patients with diabetes. Paraoxonase activity. HDL capacity to bind with PON1 is possible under specific experimental conditions, such as oxidation, addition of polyphenols, or in diabetic patients with polyphenols doses. The aim of this study was the effect of pomegranate juice (PJ) on paraoxonase and arylesterase activity of PON1.

Materials and methods: Fifty patients with type 2 diabetes mellitus consumed 200 ml of PJ daily for a period of 6 weeks. Blood was collected from the patients before and after PJ consumption after 12 h of fasting. Blood sugar, total cholesterol, triglyceride, LDL- C and HDL-C were measured by colorimetric kit method. The malondialdehyde concentration (μmol/L) was determined by thiobarbituric acid (TBA) assay. Paraoxonase and arylesterase activity of PON1 enzyme were measured using paraoxone and phenylacetate as the substrates.

Results: The concentration of fasting blood sugar, total cholesterol, LDL-C and malondialdehyde significantly (p < 0.001) decreased after the intervention. Paraoxonase and arylesterase activity of PON1 significantly (p < 0.001) increased after the intervention. There were however no significant changes in serum triglyceride and HDL-C. There was a significant positive correlation between paraoxonase and arylesterase activity of PON1 and serum HDL-C concentration . A significant negative correlation was detected between paraoxonase and arylesterase activity of PON1 and FBS.

Conclusion: It can be concluded that PJ consumption as an antioxidant may have a contribution in changing fasting blood sugar, lipid profiles, lipoprotein oxidation, and PON1 activity.
