摘 要:目的:制备姜黄素固体脂质纳米粒(Cur-SLN)。方法:用乳化蒸发-低温固化技术制备Cur-SLN,以姜黄素、泊洛沙姆188、山嵛酸甘油酯、卵磷脂用量为考察因素,以包封率为指标,用正交试验优选处方,并考察其形态、粒径、表面电位、包封率、体外释药特性。结果:优选出姜黄素、泊洛沙姆、山嵛酸甘油酯、卵磷脂的用量分别为8、320、140、320mg,所制得的脂质纳米粒为类圆球状,粒径为(134±5)nm,包封率为(67.4±1.3)%,平均表面电位值为(-23.5±1.5)mV,药物体外释放符合Higuchi方程。结论:采用乳化蒸发-低温固化技术制备Cur-SLN可行,可为开发姜黄素新型注射剂提供试验依据。OBJECTIVE: To prepare Curcumine solid lipid nanoparticles (Cur-SLN) .METHODS: Cur-SLN was prepared by emulsification evaporation - solidification at low temperature. The formulation of Cur - SLN was optimized by orthogonal experiment with the contents of curcumine, poloxamer 188, docosanoic acid glyceride lecithin used as factors and with entrapment efficiency as index; meanwhile, the appearance, particle size, surface potential, entrapment efficiency and the release profile of cureumine in vitro were studied. RESULTS: The optimized preparation conditions were as follows: the contents of curcumine, poloxamer, docosanoic acid glyceride lecithin were 8 mg,320 mg, 140 mg and 320 mg, respectively. The Cur- SLN assumed spherical shape with particle size at (134±5) nm, entrapment efficiency at (67.4±1.3)% and mean surface potential at( -23.5±1.5) inV. The release profile of curcumine in vitro fitted Higuchi equation. CONCLUSION: It is feasible to prepare Cur- SLN by emulsion evaporation- solidification at low temperature, and the study results serve as experimental evidence for developing new curcumine injection.
