Flavonoids have intense antioxidant and anti-inflammatory properties and could be used as dietary supplements in order to derive chicken meat products of improved quality. An experiment was therefore conducted to examine the effects of supplementing feed with different levels of hesperidin or naringin, flavonoids that are abundant and inexpensive by-products of citrus cultivation, on the the metabolic fingerprint of chicken plasma. Sixty, eleven day old, broilers were randomly assigned into 6 treatment groups of ten chickens each. One of the groups served as control (C) and was given a commercial basal diet, without flavonoid supplementation, whereas the other five groups were given the same diet further supplemented with hesperidin at low (750mg/kg of feed) (H1) or high (1500mg/kg) (H2) concentration or naringin at low (750mg/kg) (N1) or high (1500mg/kg) (N2) concentration or α-tocopheryl acetate (200mg/kg) (E). Plasma samples were collected 4 and 8h after the beginning of flavonoids dietary supplementation and at the end of the experiment (42 days). NMR based metabolomics using CPMG pulse sequence was implemented [1] in order to elicit information from the plasma. The spectral data was subjected to multivariate data analysis using SIMCA 13 software. In this context, supervised analysis (OPLS-DA) traced variations in the metabolic pattern according to the sustenance consumption which was attributed to specific metabolites with the application of the S-line plot. Particularly, control samples displayed higher concentration in unsaturated lipids, di-saccharides and threonine when compared to the VE, while the latter were characterized by the presence of HDL, dimethylamine and carnitine. Hesperidin (both E1 and E2) samples in contrast to control ones were characterised by increased levels of di-saccharide, threonine, creatinine, carnitine, dimethylamine and glutamine/glutamate. Narginin (both N1 and N2) samples also revealed the previous pattern and at the same time appeared to have increased levels of citrate and acetate when compared to controls. Results indicated that similar metabolic patterns were observed irrespective of the type (H or N) and level (H1 or H2, N1 or N2) of the flavonoid incorporated in broiler diet. Moreover, quantification of selected metabolites (leucine, isoleucine, valine, alanine, citrate, dimethylglycine, glutamine, lactate, threonine, glucose, fumarate, tyrosine phenylalanine, formate) was Πρόγραμμα Θαλής-«Αξιοποίηση Φυσικών Αντιοξειδωτικών στην Εκτροφή των Αγροτικών Ζώων για Παραγωγή Προϊόντων Ποιότητας»  3    also attempted using Chenomx software. N and VE samples exhibited the highest homogeneity among these results. REFERENCES: [1] NMR metabolite profiling of Greek grape marc spirits, Food Chemistry.  Charalambos Fotakis, et al.
