Background: The seeds of Macrotyloma uniflorum Lam. (Family Fabaceae) contain extractable total and tannins with reported hepatoprotective, hypocholesterolemic and antioxidant activity. In this study, dietary M. uniflorum seed, methanolic and acetone extracts (ME and AE) were examined for their bile-antilithogenic potential. Materials and Methods: Mice fed with 1% cholesterol and 0.5% cholic acid lithogenic (LG) diet for 8 weeks resulted in cholesterol super saturation in gallbladder bile, which promotes the formation of cholesterol gallstones (CGSs). Results: AE reduced the CGS incidence by 60.21%, and serum total cholesterol, triglyceride (TG), very low density lipoprotein (LDL) and LDL compared to control animals. Seed extracts at 300 mg/kg dose markedly reduced biliary cholesterol (BC) and decreased bile salt content. The ratio of BC to phospholipid which was 2.64 in the LG diet group was reduced to 1.57-1.35 in the M. uniflorum seed extracts treated groups. Liver cholesterol and TG were decreased significantly by feeding of ME and AE at 300 mg/kg dose. AE significantly reversed the changes in apolipoproteins A-I and C-II level disturbed by LG diet. Conclusions: M. uniflorum seed exerted antilithogenic influence by decreasing the cholesterol hyper-secretion into bile and increasing the bile acid output, thus decreasing the formation of LG bile in mice. The effect was maximum in the AE as it also reduced papillary proliferation of gallbladder and fatty degeneration of the liver. The potential antilithogenic effect of the AE of M. uniflorum may be due to antioxidant property of its rich total polyphenol and tannins content.
