目的优选薄膜-超声法制备双烟酸姜黄素酯固体脂质纳米粒的辅料配比。方法采用HPLC测定双烟酸姜黄素酯的含量,以双烟酸姜黄素酯固体脂质纳米粒的包封率为评价指标,通过三因素三水平Box-Bebnken响应面设计试验法筛选纳米粒辅料中硬脂酸、卵磷脂的用量及聚山梨酯-80的浓度,并确定最优处方辅料配比。结果最佳处方辅料配比为硬脂酸80 mg,卵磷脂150 mg,聚山梨酯-80(0.6%)20 mL,所得烟酸姜黄素固体脂质纳米粒包封率达65%,平均粒径为190 nm。结论用星点设计试验优化后制剂处方的双烟酸姜黄素酯固体脂质纳米粒最优处方辅料配比适合于制备双烟酸姜黄素酯固体脂质纳米粒。

OBJECTIVE: To optimize the film-ultrasonic technique for preparing nicotinate-curcumin nanoparticles. METHODS: An HPLC method was established for determination of nicotinate-curcumin. Using the entrapment efficiency of nicotinate-curcumin as the evaluation indicator, the optimum excipient formula was selected through the Box-Bebnken reponse surface design of three factors (amounts of nicotinate-curcumin and lecithin and concentration of tween-80) at three levels. RESULTS: With the established optimal formula, ie 80 mg stearic acid, 150 mg lecithin and 20 mL tween-80 (0.6%), the entrapment effi...
