Metabolic profiling in faecal water of rats. a PLS-DA score plot. b, c Plot of O-PLS-DA coefficients related to the discrimination between 1H-NMR spectra for rats treated with b HEM (top) vs. Con (bottom), and c HEM-Ca (top) vs. HEM (bottom). Metabolites are colour-coded according to their correlation coefficient, with red indicating a very strong positive correlation (r2 > 0.7). The direction of the metabolite indicates the group with which it is positively associated as labelled on the diagrams. α-glu, α-glucose; ace, acetate; β-ara, β-arabinose; β-glu, β-glucose; β-xy, β-xylose; b.a., bile acids; BCAA, branched-chain amino acids; but, butyrate; cap, caprylate; hpx, hypoxanthine; prop, propionate; suc, succinate; TMA, trimethylamine; ura, uracil; uri, uridine; U1-4, unknown compounds; 4-HPP, 3-(4-hydroxyphenyl)propionic acid; 5av, 5-aminovalerate
