Popis: The type 2 diabetes is one of the major global health issues that affects millions of people. This study evaluated the antidiabetic activity of aqueous extracts (AECP) and methanol extracts (MECP) from Ceiba pentandra trunk bark on an experimental model of type 2 diabetes (T2D). This model was induced in rats by the combination of a high-fat diet (HFD) and a single dose of streptozotocin (40 mg/kg, intraperitoneal) at the seventh day of experimentation. Diabetes was confirmed on day 10 by fasting blood glucose more than or equal to 200 mg/dL. Diabetic animals still under HFD were treated orally and twice daily, with MECP and AECP (75 and 150 mg/kg) or metformin (40 mg/kg) for 14 days. During the experiment, blood glucose and animal weights were determined. Oral glucose tolerance test was performed on day 15, followed by animals sacrifice for blood, liver, and pancreas collection. Total cholesterol and triglyceride levels were evaluated in plasma, whereas malondialdehyde (MDA), glutathione (GSH), superoxide dismutase, and catalase were quantified in tissue homogenates. AECP and MECP significantly reduced the hyperglycemia by up to 62% and significantly improved the oral glucose tolerance test. The impaired levels of cholesterol and triglycerides registered in diabetic control were significantly reversed by both extracts at all the doses used. Alterations in diabetic pancreas weight, GSH, and MDA were also significantly reversed by plant extracts. AECP and MECP possess type 2 antidiabetic effects that could result from their ability to improve the peripheral use of glucose, lipid metabolism or from their capacity to reduce oxidative stress. These finding provide a new avenue for better control and management of early or advanced T2D.
