Abstract
This study was conducted to investigate the cholesterol lowering and anti-obesity effects of an ethanol extract of broccoli sprouts (BS) in rats fed high fat diet. Male Sprague-Dawley rats weighing 150~155 g, were divided into 6 groups; a normal diet group (ND), a high fat diet group (HFD), a normal diet and BS with 200 mg/kg treated group (ND-BSL), a normal diet and BS with 400 mg/kg treated group (ND-BSH), a high fat diet and BS with 200 mg/kg treated group (HFD-BSL), and a high fat diet and BS with 400 mg/kg treated group (HFD-BSH). The body weight gain and mesenteric adipose tissue weight were increased by high fat diet, but gradually decreased to the corresponding level of ND group after administration of BS extract. The liver and epididymal adipose tissue weights of HFD group were the highest among the six groups, although the difference was not significant. Food intake was lower in high fat diet groups compared with normal diet groups. The serum ALT and AST activities that were elevated by the high fat diet were significantly decreased after BS administration. Levels of serum total cholesterol, LDL-cholesterol, triglyceride and the atherogenic index tended to be decrease in the BS administered groups compared with HFD group. However, HDL-cholesterol level in serum decreased in HFD group and markedly increased in BS administered groups. There were no differences in the contents of serum triglyceride, LDL-cholesterol and HDL-cholesterol between normal
diet groups. Levels of total cholesterol and triglyceride in liver and adipose tissues were also lower in BS administrated groups than in HFD group. The activities of heparin-releasable lipoprotein lipase (HR-LPL) and total-extractable LPL (TE-LPL) in adipose tissue were increased in HFD group compared with the BS administered groups, but those of the ND-BSL group and ND-BSH group were similar to ND group. These results suggest that BS ethanol extract may exert cholesterol-lowering effect and potentially reduce lipid storage.
