Abstract

Administration of leucodelphinidin derivative isolated from the bark of Ficus bengalensis and another flavonoid quercetin (100mg/kg/day) in hypercholesterolemic rats provoked significant reduction in serum total cholesterol, LDL-cholesterol and an increase in the HDL-cholesterol levels. Significant decrease in atherogenic index was noted in these rats treated with the different flavonoids . There was an increased concentration of total bile acids in the liver and also increase in the fecal excretion of bile acids and neutral sterols in the rats fed cholesterol containing diet as compared to those fed normal diet. Feeding the flavonoids further significantly increased the concentrations of hepatic bile acids and the fecal excretion of bile acids and neutral sterols as compared to the control cholesterol diet fed group. The activity of 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase was not inhibited by the flavonoids, instead there was an increased cholesterogenesis as was evident by an increased incorporation of labeled acetate into both free and esterfied cholesterol on treatment with leucodelphinidin and quercetin. These results demonstrated that the flavonoids exerted their hypocholesterolemic effects by increasing fecal bile acids and cholesterol excretion. Acute toxicity studies with the leucodelphinidin derivative showed no toxic reactions up to a dose of 4g/kg dose level.
