The study found that the aqueous extract of Ipomoea batatas leaves has hypolipidemic and anti-atherosclerogenic effects on diet-induced hypercholesterolemic rats, and can restore normal blood glucose and lipid levels.
Objective: Ipomoea batatas (L.) Lam. is a food plant used in African traditional medicine to treat cardiovascular diseases and related conditions. We assessed the hypolipidemic and anti-atherosclerogenic properties of the aqueous extract of I. batatas leaves in a rat model of diet-induced hypercholesterolemia. Methods: Hypercholesterolemia was induced in male Wistar rats by exclusive feeding with a cholesterol enriched (1%) standard diet for four weeks. Then, rats were treated once daily (per os) with I. batatas extract at doses of 400, 500 and 600 mg/kg or with atorvastatin (2 mg/kg), for four weeks. Following treatment, animals were observed for another four weeks and then sacrificed. Aortas were excised and processed for histopathological studies, and blood glucose level and lipid profile were measured. Results: Hypercholesterolemic animals experienced a 21.5% faster increase in body weight, significant increases in blood glucose and blood lipids (148.94% triglycerides, 196.97% high-density lipoprotein cholesterol, 773.04% low-density lipoprotein cholesterol, 148.93% very low-density lipoprotein cholesterol and 210.42% total cholesterol), and increases in aorta thickness and atherosclerotic plaque sizes compared to rats fed standard diet. Treatment of hypercholesterolemic rats with the extract mitigated these alterations and restored blood glucose and blood lipid levels to normocholesterolemic values. Conclusion: Our findings suggest that I. batatas leaves have hypolipidemic and anti-atherosclerogenic properties and justify their use in traditional medicine.
