摘 要:目的:制备姜黄素(Cur)固体脂质纳米粒(SLN)。方法:用薄膜超声法制备Cur-SLN,以mcur:m单硬脂酸甘油酯、m单硬脂酸甘油酯:m卵磷脂、聚山梨酯-80质量浓度、超声时间为考察因素,以包封率为指标,用正交试验优选处方,并考察其粒径分布、Zeta电位。结果:当mcur:m单硬脂酸甘油酯=1:3、m单硬脂酸甘油酯:m卵磷脂=1:2.5、聚山梨酯-80质量浓度2.5%、超声时间12min时,所制得的Cur-SLN平均粒径为(145.6±5)nm,Zeta电位为(-31.9±1.5)mV,包封率为(97.42±0.39)%,载药量为(7.92±0.05)%。结论:采用薄膜-超声法制备Cur-SLN可行,为开发姜黄素新型给药系统提供试验依据。Objective:To optimize technique for preparing curcumin solid lipid nanoparticles(Cur-SLN) by film-ultrasonic dispersion.Methods:The influences of various factors,such as the ratios of curcumin and monostearin,monostearin and lecithin.Taking the concentration of Tween-80 and ultrasonic time(min) as on factors and the entrapment efficiency as index,the optimum formula was selected and particle size distribution and Zeta potential were studied by orthogonal test.Results:The optimized preparation conditions were as follows:mcur-mmonostearin = 1:3;mmonostearin-mlecithin = 1:2.5;The concentration of Tween-80 was 2.5%;Ultrasonic time was 12 min.The average particle size diameter was(145.6 ± 5) nm;Zeta potential was(-31.9 ± 1.5) mV;Entrapment efficiency was(97.42 ± 0.39) %;Drug loading was(7.92 ± 0.05)%.Conclusion:It is feasible to prepare Cur-SLN by film-ultrasonic dispersion techniques and the study results provide the test evidence for developing new curcumine drug delivery system.
