Anti‑hypercholesterolaemic activity of Lipovedic and its mechanism

Meera Sumanth, S. Swetha


Objective: To illustrate the antihypercholesterolaemic mechanism of Lipovedic ‑ a polyherbal formulation. Materials and Methods: The antihypercholesterolaemic mechanism of Lipovedic (180 mg/kg, p.o) was studied by measuring the serum total cholesterol (TC), triglycerides (TG), high density lipoprotein‑cholesterol (HDL‑C), low density lipoprotein‑cholesterol (LDL‑C), very low density
lipoprotein‑cholesterol (VLDL‑C), Faecal cholesterol (FC) and bile acid excretion in triton induced hyperlipidaemic rats at 0 h, 18 h,
24 h, 40 h, and 48 h and in high cholesterol diet (HCD) induced hypercholesterolaemic rats on day 7, 14, 21 and 28. Hydroxy‑3‑Methyl Glutaryl Co‑Enzyme A (HMG CoA)/mevalonate ratio was measured in the liver homogenate for the HMG‑CoA reductase activity. Atorvastatin (7.2 mg/kg p.o) was used as reference standard. One‑way ANOVA, Post‑hock analysis by Tukey’s multiple comparison tests was done using GraphPad Prism 5. Results: Lipovedic (180 mg/kg, p.o) reduced the serum TC, TG, LDL‑C, VLDL‑C and increased the serum HDL‑C in triton treated and HCD fed rats. Lipovedic increased FC excretion. HMG CoA/Mevalonate ratio was significantly higher compared to vehicle control rats and the result was comparable with Atorvastatin (7.2 mg/kg p.o). Conclusion:
Lipovedic acts as an anti‑hypercholesterolaemic drug by: inhibition of HMG CoA reductase, increasing FC excretion and reducing dietary cholesterol absorption, increasing hepatic low density lipoprotein receptor expression and by activation of Lecithin Cholesterol Acyl Transferase and Lipoprotein lipase.
Key words: High cholesterol diet, homogenate Co‑Enzyme A reductase, hypercholesterolemia, Lipovedic, triton, carboxy methyl
