Abstract

The effect of various rice bran extracts such as water extracts (RBW), methanol extracts (RBM) and protein-fiber extracts (RPDF) on serum and liver lipid contents were investigated in rats fed with high-fat diet for 4 weeks. The increases of body weights in RPDF group were lower than those of control group. Serum total cholesterol concentrations were significantly decreased in RPDF group compared with control group. The contents of liver lipid in all three experimental groups were decreased compared to control group. Especially, total cholesterol contents of liver in RPDF group were significantly lower than those in control group. Compared to control group, the levels of thiobarbituric acid reactive substance in the livers of rats in all experimental groups were significantly reduced, but there was no significant difference among the three experimental groups.
