Beilschmiedia obscura seeds powder: Potential functional food ingredient for glycemic control in Diabetes Mellitus
Abstract
Beilschmiedia obscura seeds are used as dietary enhancers in some Cameroonian traditional dishes. They have preventive effects against metabolic disorders, but their potential effects in diabetes management have not yet been studied. This study therefore aims to evaluate the antidiabetic effect of Beilschmiedia obscura seed powder as a novel local therapeutic resource. Diabetes was induced in rats using streptozotocin, and the diabetic rats were treated with a diet supplemented with 10% B. obscura seed powder for 14 days. Fasting blood glucose were assessed weekly. Additionally, oral glucose, sucrose, or starch tolerance tests were conducted in normoglycemic rats. Finally, in vitro study to investigate glucose adsorption capacity, and glucose uptake in non-insulin-dependent cells (yeast) and insulin-dependent cells (skeletal muscle cells) was carried out. B. obscura seed powder significantly decrease glycemia of diabetic rats (81.71% of the initial value at 14th day). It significantly restored hepatic glycogen levels in diabetic rats. Additionally, B. obscura seeds powder significantly reduced glycemic peak (about 2-fold) compared to normal control following oral glucose, sucrose, and starch administration. In vitro, B. obscura seeds powder showed the ability to scavenge glucose (up to 48.27% at 10mg/mL) and to stimulate glucose uptake both into non-insulin-dependent cells (up to 25.45% at 10mg/mL) and insulin-dependent cells (up to 35.40% at 7.5mg/mL). These findings suggest that B. obscura seeds powder has multifaceted actions in modulating blood glucose, which position it as a promising plant-based intervention for glycemic control, especially in resource-limited settings where affordable natural therapies are critically needed.
