Synergistic effect of Moringa oleifera leaf extract on glycemic control and lipid profile: a preclinical evaluation
Abstract
Background: The global incidence of Type-2 diabetes is escalating, driven by lifestyle changes, urbanization, and dietary habits, particularly in developing countries. This has led to a growing demand for novel, natural therapeutic agents to effectively manage this chronic condition. Moringa freeze-dried extract powder (MFDP), a plant widely recognized for its nutritional profile and medicinal properties, has shown promise in treating metabolic disorders.
Methods: The Moringa oleifera leaf extract was analyzed using advanced analytical technique, revealing substantial concentrations of bioactive compounds including flavonoids, polyphenols, and quercetin. In addition, its antidiabetic and anti-hyperlipidemia effect were evaluated through rat trials, enabling assessment of glucose regulation and lipid profile improvement. This study also assessed the impact of freeze-drying on the physicochemical composition of MFDP, considering regional and environmental variation to ensure local relevance of the findings.
Results: In diabetic rats, the MFDP significantly (p ≤ 0.05) reduced blood glucose levels (random: 343 ± 0.02 mg/dL to 171 ± 0.03 mg/dL; fasting: 243.21 ± 0.03 mg/dL to 98.2 ± 0.02 mg/dL) and HbA1c levels (5.4 ± 0.15 %). It also improved lipid profiles by lowering total cholesterol (85.17 ± 5 mg/dL), triglycerides (94.11 ± 10.4 mg/dL), and LDL concentrations (27.82 ± 7.1 mg/dL) while increasing HDL levels (41.14 ± 2.5 mg/dL). Additionally, MFDP treatment enhanced liver glycogen (18.07 ± 3 mg/g to 43.68 ± 2.5 mg/g), indicating improved hepatic glucose utilization.
Conclusion: The findings underscore the dual therapeutic potential of MFDP in managing metabolic disorders like diabetes and hypercholesterolemia. Given the increasing prevalence of these conditions, especially in regions like South Asia, further research is needed to explore the molecular mechanisms underlying these beneficial effects and to validate the use of Moringa oleifera as a natural therapeutic agent.
