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: m_cur-m_monostearin = 1︰3; m_{monostearin -}m_lecithin = 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.
