Determination of lipid lowering properties of methanol extract of Tephrosia villosa against high fat diet induced hyperlipidemia in wistar rats

Abstract

Objectives: The present study was performed to determine hypolipidemic potentials of methanol extract of Tephrosia villosa against high fat diet induced hyperlipidemia in wistar rats. Methods: Defatted powdered drug of ariel parts of Tephrosia villosa was subjected to methanol extraction using soxhlet extractor. The high fat diet induced hyperlipidemia in rat model was used for the present investigation in which all experimental rats were ingested with high fat diet (HFD) for entire period of study and were also administered with methanol extract for 21 days. Blood samples were collected from all the animals on day 21st after one hour of administration of the drugs and serum lipid profile (total cholesterol, triglycerides, HDL, LDL and IDL) was estimated. All animals were sacrificed after the blood sampling and liver samples were collected. Results: The rats of therapeutic groups ingested with extract of Tephrosia villosa and standard drug atorvastatin have shown significant reduction in serum cholesterol, serum triglycerides, LDL and increase in HDL indicating its ability to attenuate the effects of high fat diet. Conclusion: The methanol extract of Tephrosia villosa shown significant hypolipidemic effects against high fat diet induced hyperlipidemia wistar rats by inhibiting cholesterol synthesis in liver.
