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.
