TITLE: | Optimization of the Formulation of Curcumin Transethosomes |
摘要: | 目的:优化姜黄素(CUR)醇传递体(CUR-TEs)的处方。方法:采用高效液相色谱法测定CUR-TEs中CUR的含量。采用注入法制备CUR-TEs,并以包封率和载药量的综合评分为指标,在单因素实验的基础上,采用Box-Behnken设计-响应面法对其处方进行优化及验证,然后考察以最优处方制得的CUR-TEs的性质。结果:CUR-TEs的最优处方为卵磷脂用量4%、CUR用量0.13%、1,2-丙二醇用量25%、聚山梨酯80用量1%。最优处方的验证实验结果显示,CUR-TEs包封率和载药量的综合评分为93.04±2.16,与预测值(91.19)的相对误差为2.03%。以最优处方所制得的CUR-TEs的包封率为(91.17±1.35)%、载药量为(0.94±0.02)%、粒径为(190.64±15.97)nm、多分散系数(PDI)为0.086±0.007、Zeta电位为(-12.74±1.60)mV。结论:优化后的CUR-TEs处方稳定性良好,具有可行性和可重复性;所制得的CUR-TEs具有较好的稳定性。 |
ABSTRACT: | OBJECTIVE:To optimize the formulation of Curcumin (CUR)transethosomes(CUR-TEs). METHODS :The contents of CUR in CUR-TEs were determined by HPLC. CUR-TEs were prepared by injection method. Using comprehensive score of encapsulation efficiency and drug loading as index ,based on signal factor test ,Box-Behnken design-response surface method was used to optimize and validate the formulation. The property of CUR-TEs prepared by the optimal formulation was investigated. RESULTS:The optimal formulation of CUR-TEs was as follows as lecithin of 4%,CUR of 0.13%,1,2-propylene glycol of 25%,tween-80 of 1%. Results of validation test of optimal formulation showed that comprehensive score of encapsulation efficiency and drug loading of CUR-TEs was 93.04±2.16,relative error of which to predicted value (91.19)was 2.03%. The encapsulation efficiency of CUR-TEs prepared by optimal formulation was (91.17±1.35)%,and its drug loading was (0.94± 0.02)%. The particle size was (190.64±15.97)nm with polydispersity index of 0.086±0.007,and Zeta potential was (-12.74± 1.60)mV. CONCLUSIONS :The optimized formulation of CUR-TEs is stable ,feasible and repeatable ,with good stability. |
