聚山梨酯80修饰的天麻素脂质体制备研究
Study on the preparation technology of the gastrodin liposomes modified with polysorbate 80
摘要
Abstract
Objective:To optimize the formulation of the gastrodin liposomes modified with polysorbate 80 with thin film ultrasonic method by Box-Behnken design and response surface method.Methods:The influence fac-tors included the concentration of lipid,the ratio of phosphatidylcholine to cholesterol,the ratio of lipid to drug.The evaluation parameters included entrapment efficiency,drug loading.Experiments were done on the theory of Box-Behnken design.The data were simulated and the possibly optimal formulation was predicted by response surface method.Results:The optimal formulation were as follow as the concentration of lipid was 16 mg/ml,phosphatidyl choline-cholesterol ratio of 3.05:1,lipid-drug ratio of 5:1.According to the optimal conditions,the mean diameter, polydis persity index,zeta potential of the liposome were(97.63 ± 1.53)nm,(0.27 ± 0.02)and(-14.1 ± 0.83)mv,en-trapment efficiency,drug loading were(35.17 ± 0.25)% and(7.03 ± 0.05)%,respectively.Conclusion:The prepa-ration of liposomes bythin film ultrasonic method is simple and feasible.The gastrodin liposomes modified with polysorbate 80 were pale blue.The characterization results showed that the liposomes were spherical in shape and stable in nature,which lay the foundation for further research on in vivo research.关键词
