Green Tea Extract Loaded into Solid Lipid Nanoparticles

The aim of this study was to synthesize by high shear homogenization method and to characterize new solid lipid nanoparticles loaded with green tea extract, nanoparticles which show high antioxidant activity. In this respect, cetyl palmitate and glyceryl stearate were used as solid lipids in combination with two nonionic surfactants, Tween20 and Tween80 and an ionic surfactant as lecithin. The obtained solid lipid nanoparticles have been firstly characterized by particle diameter and physical stability using dynamic light scattering method. The particle morphology was examined by transmission electron microscopy. The antioxidant and antimicrobial properties of new developed nano-materials have been also evaluated.
