Main phenolic compounds present in the rosemary extract (RE).
Chromatogram (285 nm) corresponding to the HPLC-DAD-MS analysis of the RE extract. The structure and peak identification of carnosol (peak 10) and CA (carnosic acid, peak 14) are indicated. Peak numbers correspond to each of the phenolic compounds identified in the extract and listed in Table 1.

Figure 2.
Effects of the consumption of RE on plasma levels of the hepatic enzymes ALP and ALT (U/L) in Zucker female rats.
Lean (Le) and obese (Ob) rats fed the control diet (CT) or the diet supplemented with RE (RE). Data are presented as the mean value ± SD (n = 7 for lean animals and n = 5 for obese animals). * P<0.05 compared to their respective CT values.
Figure 3.
Effects of the consumption of RE on body weight (g) and food utility index (FUI) in Zucker female rats.
Lean (Le) and obese (Ob) rats were fed the control diet (CT) or the diet supplemented with 0.05% of RE (RE) for 64 days. Data are presented as the mean value ± SD (n = 7 for lean animals and n = 5 for obese animals). * P<0.05, ** P<0.01 compared to their respective CT values.
Figure 4.
Effects of the consumption of RE on plasma levels of TGs and total cholesterol (mmol/L) in Zucker female rats.
Lean (Le) and obese (Ob) rats fed the control diet (CT) or the diet supplemented with RE (RE). Data are presented as the mean value ± SD (n = 7 for lean animals and n = 5 for obese animals). ** P<0.01, *** P<0.001 compared to their respective CT values.

Final body weight, organ and gut content weight for lean (Le) and obese (Ob) female Zucker rats fed the control diet (CT) or the diet supplemented with RE enriched in CA (40%).
Figure 5.
Effects of the consumption of RE on lipase activity in Zucker female rats.
Lean (Le) and obese (Ob) rats fed the control diet (CT) or the diet supplemented with RE (RE). Activity (expressed in nkats/g) was measured as the hydrolysis of PNPB in a) stomach content, b) duodenum content, c) small intestine (jejunum+ileum) content, d) liver and e) pancreas. Data are presented as the mean value ± SD (n = 7 for lean animals and n = 5 for obese animals). # P<0.1, * P<0.05 and ** P<0.01 compared to their respective CT values.
