The purpose of this study was to determine the effects of dried Dendropanax morbifera leaf extracts on lipid profiles of mice fed a high-fat and -cholesterol diet (HFCD). ICR mice were divided into six groups based on mice fed AIN-93G diet (Normal), HFCD (Control), HFCD+100 mg/kg/d of D. morbifera leaf aqueous extract (DA-100), HFCD+200 mg/kg/d of D. morbifera leaf aqueous extract (DA-200), HFCD+100 mg/kg/d of D. morbifera leaf ethanol extract (DE-100), or HFCD+200 mg/kg/d of D. morbifera leaf ethanol extract (DE-200) for 7 weeks. The final body weights of mice fed D. morbifera extracts were all lower than those of the control group. Mice treated with D. morbifera extracts showed significantly reduced plasma and hepatic triglyceride (TG), total cholesterol (TC), and low-density lipoprotein cholesterol levels, along with increased plasma high-density lipoprotein cholesterol level. Fecal TG level was higher in DE-100 and DE-200 groups and TC level was significantly higher in the DA-200 and DE-200 groups. Relative liver weight, spleen weight, and testicle fat weight in mice treated with D. morbifera were reduced compared to the control group. Plasma insulin, aspartate transaminase, and alanine transaminase levels of experimental groups were also lower than those of the control group. All mice treated with D. morbifera extracts had lower malondialdehyde (MDA) content and higher superoxide dismutase (SOD) activity than the control group. Particularly MDA levels of the DA-200 and DE-200 groups and SOD levels of the DE-200 group were identical to levels of the normal group. These results suggest that D. morbifera extracts have lipid improvement effects in mice fed a HFCD.
