摘要:

以蛋黄卵磷脂、胆固醇和神经酰胺为成膜材料,采用薄膜分散法制备胶原蛋白神经酰胺脂质体(CO-CS)。以包封率为响应值,以药脂比、膜材比、超声时间和水合时间为影响因素对工艺进行优化。结果表明,当药脂比为1:16、超声时间为8.5 min、膜材比为4.3:1时,包封率可达90.73%。在此条件下,样品的粒径为(206.63±2.06) nm,聚合物分散性指数(polymer dispersity index,PDI)为0.187±0.010,Zeta电位为(-34.90±0.82) mV。避光保存60 d后,CO-CS的包封率为87.2%,粒径为(223.70±1.85) nm、PDI为0.174±0.013、Zeta电位为(-33.51±2.10) mV。结果表明,本研究制备的CO-CS包封率高,稳定性良好,制备工艺合理可行。

Abstract:

In this study, egg yolk lecithin, cholesterol,and ceramide were used as film-forming materials to prepare collagen ceramide liposomes (CO-CS) by the thin film dispersion method. To optimize the process, encapsulation efficiency was used as the response value, and it was evaluated by influencing factors such as drug-lipid ratio, film-material ratio, ultrasonic time, and hydration time. Results showed that encapsulation efficiency reached 90.73% when the drug-lipid ratio, film-material ratio, and ultrasonic time were 1:16, 4.3:1, and 8.5 min, respectively. Under these conditions, the particle size, polymer dispersity index (PDI), and zeta potential of CO-CS were(206.63±2.06) nm, 0.187±0.010, and (34.90±0.82) mV, respectively. After 60 days of storage at room temperature in the dark, the encapsulation efficiency was 87.2 %. Furthermore, the particle size, PDI, and zeta potential of CO-CS changed to (223.70±1.85) nm, 0.174±0.013, and (33.51±2.10) mV, respectively. In summary, CO-CS produced in this study revealed high encapsulation efficiency and good stability, and the preparation process is reasonable and feasible.

Key words: collagen, ceramide liposome, response surface, encapsulation efficiency
