摘要: 本研究基于食品级玉米醇溶蛋白与阿拉伯胶构建槲皮素-山柰酚纳米递送体系,实现双成分的协同包封。结果表明,两活性成分最佳配比为2∶1,载体比例为1∶1,所得纳米颗粒粒径小、稳定性高。表征分析证实包封成功,纳米体系在不同环境中稳定性良好且具有胃肠缓释特性。动物实验表明,槲皮素-山柰酚纳米递送体系可显著降低糖尿病小鼠血糖水平,改善胰岛素抵抗与脂代谢紊乱,增强抗氧化能力并减轻脏器损伤。该研究为天然降血糖成分的高效递送提供了新策略,具有良好应用前景。

Abstract: This study utilized food-grade zein and gum arabic to construct a quercetin-kaempferol nanodelivery system (QUE-KAE-NPs) for synergistic encapsulation and targeted delivery. The optimal ratio of QUE to KAE was determined to be 2:1, and the optimal ratio of zein and gum arabic was 1:1, yielding nanoparticles with small particle size and high stability. Characterization confirmed successful encapsulation, and the nanosystem demonstrated excellent stability under various conditions and sustained-release properties in the gastrointestinal tract. Animal studies revealed that QUE-KAE-NPs significantly reduced blood glucose levels in diabetic mice, improved insulin resistance and lipid metabolism disorders, enhanced antioxidant capacity, and mitigated organ damage. This research provides a novel strategy for the efficient delivery of natural hypoglycemic compounds, with promising application prospects.
