Solid Lipid Nanoparticles (SLN) have been prepared by high-pressure homogenization and optimized in order to protect ferulic acid from Ferula assa-foetida L. extract. The influence of lipid surfactant concentration on the mean particle size (Z-Ave), polydispersity index (PDI), zeta potential (ZP) SLN was analyzed. In addition, other parameters for preparation acid-loaded nanoparticles, such as ...
