ABSTRACT
Objective:
To explore the effects of the process parameters of film dispersion-ultrasonic method on particle diameters and encapsulation efficiency of solid lipid nanoparticles of nicotinate-curcumin in order to obtain the process parameters resulting in smaller particle diameters and higher encapsulation efficiency .Methods:
The content of nicotinate-curcumin was determined by HPLC.With the particle diameters and encapsulation efficiency of solid lipid nanoparticles of nicotinate -curcumin as the evaluation in-dicators , the process parameters of film dispersion-ultrasonic method were optimized by orthogonal experimental design and 95%confi-dence interval overlap method as the statistical analysis .Results:
The optimum technological parameters of the solid lipid nanoparticles were as followsthe water bath temperature was 40℃and the rotation speed of eggplant bottle was 80 r· min-1 .The average particle size of solid lipid nanoparticles was 107.8 nm, polymer dispersity index ( PDI) was 0.583, and the encapsulation efficiency was 68.91%.Conclusion:
The rotation speed of eggplant shaped bottle has notable influence on the particle diameters of solid lipid nanop -articles of nicotinate-curcumin prepared by film dispersion-ultrasonic method , while the water-bath temperature shows great influence on the encapsulation efficiency .Under the optimum conditions , it is possible to obtain the solid lipid nanoparticles with relatively smaller average particle diameters and higher encapsulation efficiency .
