Ameliorative effect of hydro-methanolic extract from roots of Rauwolfia serpentina on some biochemical parameters of type 1 diabetic mice

Abstract

Present work seeks to investigate the biochemical parameters in terms of hypoglycemic and hypolipidemic effects of hydro-methanolic roots extract (HyMREt) of Rauwolfia serpentina in type 1 (alloxan induced) diabetic mice. Animals were divided into seven groups, four control groups, and three were test groups (HyMREt at 50, 100, & 150mg/kg). Each treatment was repeated for 14 days regularly in all seven respective groups and afterwards the body weights, fasting blood glucose (FBG), insulin, and serum lipid levels were determined. Total body weights of diabetic mice treated with HyMREt extract were dose dependently (p≤0.05) improved. FBG of test groups were significantly (p ≤ 0.0001) reduced in comparison with diabetic controls which displayed elevated fasting blood glucose level. The insulin levels of HyMREt treated groups were significantly (p≤0.0001) higher than those of diabetic controls. Lower triglyceride (TG), total cholesterol (TC), low density lipoprotein cholesterol (LDL-c) and very low density lipoprotein cholesterol (VLDL-c) whereas elevated level of high density lipoprotein cholesterol (HDL-c) were observed in test dose treated groups. In comparison with diabetic controls, the converse levels of serum lipid were observed. Significant improvement in cardio- protective indices and coronary risk index was also observed. Findings of present study support the hypoglycemic and hypolipidemic potential of HyMREt of R. serpentina.
