Objective:To compare the therapeutic effect of different animal bile powders on lipid metabolism disorders induced by high-fat diet in rats,and analyze the bioactive components of each animal bile powder.Methods:Sixty Sprague-Dawley rats were randomly divided into 6 groups(n=10):normal diet control group,high-fat diet model group,high-fat diet groups orally treated with bear,pig,cow and chicken bile powders,respectively.Serum biochemical markers from the abdominal aorta in each group were analyzed.Changes in the body weight and liver weight were recorded.Pathohistological changes in the livers were examined.High performance liquid chromatography coupled with quadrupole time-of-flight tandem mass spectrometry was used to determine the composition of bioactive components in each animal bile powder.Results:Treatment with different types of animal bile powders had different inhibitory effects on high-fat diet-induced increase of body weight and/or liver weight in rats,most notably in bear and pig bile powders(P＜0.05).High-fat diet induced lipid metabolism disorder in rats,which could be reversed by treatment with all kinds of bile powders.Bear bile and chicken bile showed the most potent therapeutic effect against lipid metabolism disorder.Cow and bear bile effectively alleviated high-fat diet induced liver enlargement and discoloration,hepatocyte swelling,infiltration of inflammatory cells and formation of lipid vacuoles.Bioactive component analysis revealed that there were significant differences in the relative content of taurocholic acid,taurodeoxycholic acid and ursodeoxycholic acid among different types of animal bile.Interestingly,a unique component with molecular weight of 496.2738 Da,whose function has not yet been reported,was identified only in bear bile powder.Conclusions:Different animal bile powders had varying therapeutic effect against lipid metabolism disorders induced by high-fat diet,and bear bile powder demonstrated the most effective benefits.Bioactive compositions were different in different types of animal bile with a novel compound identified only in bear bile powder.
