title: Antidyslipidemic activity of polyprenol from Coccinia grandis in high-fat diet-fed hamster model.
abstract: Ethanol extract of Coccinia grandis (L.) Voigt showed significant triglyceride (TG) and cholesterol-lowering effects in dyslipidemic hamster model. Ethanolic extract was fractionated into chloroform, n-butanol and water-soluble fractions and were evaluated. Activity was proved to be concentrated in chloroform-soluble fraction. Chloroform-soluble fraction containing active component was subjected to repeated column chromatography, furnished a polyprenol characterized as C(60)-polyprenol (1) isolated for the first time from this plant. It significantly decreased serum TG by 42%, total cholesterol (TC) 25% and glycerol (Gly) 12%, accompanied HDL-C/TC ratio 26% in high-fat diet (HFD)-fed dyslipidemic hamsters at the dose of 50mg/kg body weight. Results are comparable to standard drug fenofibrate at the dose of 108 mg/kg. Based on these investigations, it was concluded that the compound polyprenol (1) isolated from leaves of C. grandis possess marked antidyslipidemic activity.
