Quercetin loaded Poly (e caprolactone; PCL) nanoparticles were prepared by the solvent displacement method. The influences of formulation variables (polymer and surfactant concentration) were investigated. The results of formulations F1-F9 showed Particle size (nm) in a different medium ranged from 189.10 ± 0.28 to 252.14 ± 2.32 in 0.1 N HCl and 184.06 ± 3.84 to 288.54 ± 2.86 in phosphate buffer pH 7.4, Dissolution efficiency (%) of 46.42 ± 5.42 to 72.20 ± 0.68 and drug loading (%) of 7.18 ± 0.25 to 9.27 ± 0.50. High Resolution-Transmission Electron Microscopy image represents the spherical and smooth surface of nanoparticles. The results suggested that, quercetin loaded polymeric nanoparticles may be the viable strategy for controlled release for more than 48 hours, and improves the physical stability of quercetin.
