Antioxidant and Hypolipidemic Effects of Ipomoea batatas L and Pandanus conoideus Lam Combination on Rats Fed with High Cholesterol Diet

Abstract

BACKGROUND: Chronic hypercholesterolemia is an important predisposing factor of cardiovascular diseases. The underlying process is commonly associated with oxidative stress. AIM: This study aimed to evaluate the effects of Ipomoea batatas (IB) L tablet and Pandanus conoideus (PC) Lam extract against oxidative stress and lipid profile in rats. METHODS: This study used a pre- and post-test control group design. Wistar male rats were randomized into four groups consisting of seven rats each. The groups were control group, PC Lam extract 0.4 cc/rat/day (PC group), IB L tablet 200 mg/rat/day (IB group), and PC 0.2 cc+IB 200 mg/rat/day (PC+IB group). All groups were received high cholesterol diet for 4 weeks. The blood samples at baseline and the end of this study were used for the lipid profile, superoxide dismutase (SOD), and malondialdehyde (MDA) examination. The result was then analyzed with an Analysis of Variance test. RESULTS: There were significant differences in changes of total cholesterol, Low-density lipoprotein, triglycerides, high-density lipoprotein, MDA, and SOD in the treatment group (PC, IB, PC+IB) compared to the control (p < 0.001). The decrease of MDA and increase of SOD were mainly found in the PC+IB group compared to the PC group and IB group (p < 0.05). The changes in lipid profiles were mainly found in the PC+IB group and PC group compared to the IB group (p < 0.05). CONCLUSION: Administration of PC and IB combination is an effective hypolipidemic agent. This combination has superior antioxidant activity compared to the single-agent (PC or IB) and control.
