Abstract:

SCOPE: The aim of the present work was to determine new biomarkers of the biological effects of hesperidin in orange juice (OJ) applying a nontargeted metabolomics approach validated by targeted metabolomics analyses of compliance biomarkers.

METHODS AND RESULTS: Plasma/serum and urine targeted (HPLC-MS/MS) and untargeted (H-NMR) metabolomics signatures were explored in a subsample with pre- and stage-1 hypertension subjects of the CITRUS study (N = 159). Volunteers received 500 mL/day of control drink, OJ, or hesperidin-enriched OJ (EOJ) for 12-weeks. A 6-h postprandrial study was performed at baseline. Targeted analyses revealed plasma and urine hesperetin 7-O-β-D-glucuronide as the only metabolite differing between OJ and EOJ groups after 12-weeks consumption, and inurine is correlated with a decreased systolic blood pressure level. The nontargeted approach showed that after single dose and12-weeks consumption of OJ and EOJ changed several metabolites related with an anti-inflammatory and antioxidant actions, lower blood pressure levels and uraemic toxins.

CONCLUSIONS: Hesperetin 7-O-β-D-glucuronide could be a candidate marker for distinguishing between the consumption of different hesperidin doses at 12-weeks consumption as well as a potential agent mediating blood pressure reduction. Moreover, changes in different endogenous metabolites could explain the mechanisms of actionand the biological effects of hesperidin consumption. This article is protected by copyright.
