摘 要 目的:優(yōu)化姜黃素(CUR)醇傳遞體(CUR-TEs)的處方。方法:采用高效液相色譜法測定CUR-TEs中CUR的含量。采用注入法制備CUR-TEs,并以包封率和載藥量的綜合評分為指標,在單因素實驗的基礎(chǔ)上,采用Box-Behnken設(shè)計-響應面法對其處方進行優(yōu)化及驗證,然后考察以最優(yōu)處方制得的CUR-TEs的性質(zhì)。結(jié)果:CUR-TEs的最優(yōu)處方為卵磷脂用量4%、CUR用量0.13%、1,2-丙二醇用量25%、聚山梨酯80用量1%。最優(yōu)處方的驗證實驗結(jié)果顯示,CUR-TEs包封率和載藥量的綜合評分為93.04±2.16,與預測值(91.19)的相對誤差為2.03%。以最優(yōu)處方所制得的CUR-TEs的包封率為(91.17±1.35)%、載藥量為(0.94±0.02)%、粒徑為(190.64±15.97) nm、多分散系數(shù)(PDI)為0.086±0.007、Zeta電位為(-12.74±1.60) mV。結(jié)論:優(yōu)化后的CUR-TEs處方穩(wěn)定性良好,具有可行性和可重復性;所制得的CUR-TEs具有較好的穩(wěn)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.

姜黃素(curcumin,CUR)是從姜科植物姜黃Curcuma Longa L.的干燥根莖中提取出來的一種多酚類脂溶性化合物[1],目前被廣泛應用于醫(yī)藥領(lǐng)域中。研究表明,CUR具有抗炎、抗病毒、抗血栓、抗氧化、抗腫瘤等藥理作用[1-3],可用于糖尿病[4]、肝臟疾病[5]、胃腸道疾病[6]、肺部疾病[7]、皮膚病[8-10]的治療。然而,CUR的水溶性和穩(wěn)定性較差[11],極大地限制了其應用。為此,改善CUR的溶解度和穩(wěn)定性一直是研究熱點。目前,已有多種方法被用于解決CUR水溶性差、穩(wěn)定性差的問題,如通過使用有機溶劑或表面活性劑來提高CUR的溶解度,通過添加抗氧化劑來改善CUR的穩(wěn)定性,通過應用納米載體的包封技術(shù)來提高CUR的溶解度和穩(wěn)定性等[12-13]。
