Antidyslipidemic activity of furano-flavonoids isolated from Indigofera tinctoria

Flavonoids appear to play a major role in reducing the risk of cardiovascular diseases by decreasing the blood lipid levels. In continuation of our drug discovery program on antidyslipidemic agents we have isolated three furano-flavones 1–3 and a rare flavonol glycoside 4 from the aerial parts of Indigofera tinctoria. Our results disclose that the treatment with diastereomeric flavonoid mixture 1 and 2 (80:20) significantly decreased the plasma triglycerides (TG) by 60%, total cholesterol (TC) 19%, glycerol (Gly) 13%, and free fatty acid (FFA) 25% accompanied with increase in high density lipoproteins-cholesterol (HDL-C) by 8% and HDL-C/TC ratio 36% in high fat diet (HFD) fed dyslipidemic hamsters at the dose of 50 mg/kg body weight. The flavonoid 3 has exhibited moderate antidyslipidemic activity.
