Abstract

Abstract Kaempferol (KPF) is a flavonoid compound, which has a variety of pharmacological activities, and widely exists in daily diet. However, its application is limited due to poor solubility. Citric acid (CA) is a common food additive with high solubility. In this study, solid dispersion (SD) was prepared with CA as the carrier to improve the solubility of KPF. KPF-CA-SD (weight ratio 1:20) was obtained by ultrasonic for 20 min at 40 °C. The in vitro dissolution of KPF in SD was increased from about 50% to more than 80%. The physicochemical characterizations were analyzed by X-ray diffraction, differential scanning calorimetry, Fourier transform infrared spectroscopy, and scanning electron microscope. In hyperuricemia mice, KPF-SD (equivalent to 100 mg/kg KPF) can effectively reduce serum uric acid and exert nephroprotective effects. In conclusion, the preparation of SD with CA might provide a safe and effective selection to facilitate application of KPF in food and medicine.

应用柠檬酸作为固体分散载体，提高山奈酚的溶出度和降尿酸效果

山奈酚是一种黄酮类化合物，具有多种药理活性，广泛存在于日常饮食中。然而，由于溶解性差，其应用受到限制。柠檬酸是一种常见的高溶解度食品添加剂。本研究以CA为载体制备了固体分散体（SD），以提高KPF的溶解度。通过在40°C下超声20分钟获得KPF-CA-SD（重量比1:20）。KPF在SD中的体外溶出度从约50%增加到80%以上。通过X射线衍射、差示扫描量热法、傅立叶变换红外光谱和扫描电子显微镜对其理化性质进行了分析。在高尿酸血症小鼠中，KPF-SD（相当于100mg/kg KPF）可以有效降低血清尿酸并发挥肾保护作用。总之，用CA制备SD可能为促进KPF在食品和药物中的应用提供一种安全有效的选择。
